elf: Add _dl_find_object function
It can be used to speed up the libgcc unwinder, and the internal
_dl_find_dso_for_object function (which is used for caller
identification in dlopen and related functions, and in dladdr).
_dl_find_object is in the internal namespace due to bug 28503.
If libgcc switches to _dl_find_object, this namespace issue will
be fixed. It is located in libc for two reasons: it is necessary
to forward the call to the static libc after static dlopen, and
there is a link ordering issue with -static-libgcc and libgcc_eh.a
because libc.so is not a linker script that includes ld.so in the
glibc build tree (so that GCC's internal -lc after libgcc_eh.a does
not pick up ld.so).
It is necessary to do the i386 customization in the
sysdeps/x86/bits/dl_find_object.h header shared with x86-64 because
otherwise, multilib installations are broken.
The implementation uses software transactional memory, as suggested
by Torvald Riegel. Two copies of the supporting data structures are
used, also achieving full async-signal-safety.

microblaze: Add missing implementation when !__ASSUME_TIME64_SYSCALLS
In commit
a92f4e6299fe0e3cb6f77e79de00817aece501ce ("linux: Add time64
pselect support"), a Microblaze specific implementation of
__pselect32() was added to cover the case of kernels < 3.15 which lack
the pselect6 system call.
This new file sysdeps/unix/sysv/linux/microblaze/pselect32.c takes
precedence over the default implementation
sysdeps/unix/sysv/linux/pselect32.c.
However sysdeps/unix/sysv/linux/pselect32.c provides an implementation
of __pselect32() which is needed when __ASSUME_TIME64_SYSCALLS is not
defined. On Microblaze, which is a 32-bit architecture,
__ASSUME_TIME64_SYSCALLS is only true for kernels >= 5.1.
Due to sysdeps/unix/sysv/linux/microblaze/pselect32.c taking
precedence over sysdeps/unix/sysv/linux/pselect32.c, it means that
when we are with a kernel >= 3.15 but < 5.1, we need a __pselect32()
implementation, but sysdeps/unix/sysv/linux/microblaze/pselect32.c
doesn't provide it, and sysdeps/unix/sysv/linux/pselect32.c which
would provide it is not compiled in.
This causes the following build failure on Microblaze with for example
Linux kernel headers 4.9:
[...]/build/libc_pic.os: in function `__pselect64':

However if a audit modules tries to dlmopen an inexistent module,

This is different than dlopen, since first it will not use

So the assert on _dl_open can not really be seen if the state is

Remove upper limit on tunable MALLOC_MMAP_THRESHOLD
The current limit on MALLOC_MMAP_THRESHOLD is either 1 Mbyte (for

patch dated 2006 (15 years ago). Attempts to set the threshold higher

The default behavior is appropriate for many highly parallel
applications where many processes or threads are sharing RAM. In other
situations where the number of active processes or threads closely
matches the number of cores, a much higher limit may be desired by the
application designer. By today's standards on personal computers and
small servers, 2 Gbytes of RAM per core is commonly available. On
larger systems 4 Gbytes or more of RAM is sometimes available.
Instead of raising the limit to match current needs, this patch
proposes to remove the limit of the tunable, leaving the decision up
to the user of a tunable to judge the best value for their needs.
This patch does not change any of the defaults for malloc tunables,

Also, to avoid adding both LFS and 64 bit time support on internal
tests they are moved to a newer 'testsuite-internal' module. It
should be similar to 'nonlib' regarding internal definition and
linking namespace.
This patch also enables LFS and 64 bit support of libsupport container
programs (echo-container, test-container, shell-container, and
true-container).
Checked on x86_64-linux-gnu and i686-linux-gnu.
