mips: clear condition bit 23 in fpu too

Original message:

This test fails since the read back fpu control word is 0x80000 instead

rename V variable to lib-version
Due to the rise of kbuild type build systems (as the Linux kernel is a
popularly emulated environment), the V variable has become common as a
knob for controlling verbosity. Unfortunately, if you run `make V=1`
with glibc during install, it fails with weird errors due to the glibc
build already using this variable for versioning information.
Granted, overriding this variable in the glibc context makes no sense
so people shouldn't be doing it, but when paired with build frameworks
that like to use one set of options for all packages, glibc starts to
stick out as an oddball (in that it fails). Considering it's easy
enough to rename (it's used in just one place), let's do so.

split assume pipe2/dup3/sock_cloexec knobs
We can't assume sock_cloexec and pipe2 are bound together as the former
defines are found in glibc only while the latter are a combo of kernel
headers and glibc. So if we do a runtime detection of SOCK_CLOEXEC, but
pipe2() is a stub inside of glibc, we hit a problem. For example:
main()
{
getgrnam("portage");
if (!popen("ls", "r"))
perror("popen()");
}
getgrnam() will detect that the kernel supports SOCK_CLOEXEC and then set
both __have_sock_cloexec and __have_pipe2 to true. But if glibc was built
against older kernel headers where __NR_pipe2 does not exist, glibc will
have a ENOSYS stub for it. So popen() will always fail as glibc assumes
pipe2() works.
While this isn't too much of an issue for some arches as they added the
functionality to the kernel at the same time, not all arches are that
lucky.
Since the code already has dedicated names for each feature, delete the
defines wiring these three features together and make each one a proper
dedicated knob.
We've been carrying this in Gentoo since glibc-2.9.
