lsof: define linux C library type when using eglibc

lsof tries to compile a temp c source file and execute the binary to
determine linux C library type (file Configure, line 2689-2717).
It is inpracticable for cross-compilation and may have build issue on
some distros since it depends on host settings.

Fix below error when building for 64bit target on 64bit host:
[...]
| dsock.c:481:44: error: 'TCP_LISTEN' undeclared (first use in this function)
| dsock.c:482:45: error: 'TCP_CLOSING' undeclared (first use in this function)
[...]
| make: *** [dsock.o] Error 1

The actual issue exists in do_configure:
[...]
Testing C library type with cc ... done
Cannot determine C library type; assuming it is not glibc.

Which is in turn caused by missing 'gnu/stubs-32.h" when compiling
the temp c source file on host:
[...]
fatal error: gnu/stubs-32.h: No such file or directory compilation terminated.

file gnu/stubs-32.h is provided by 32bit glibc.
