[RFC][PATCH] * bits/confname.h: Define _CS_POSIX_V7_THREADS_CFLAGS, _CS_POSIX_V7_THREADS_LDFLAGS

Sourceware - libc-alpha mailing list
I would like to add these enums in order to conform to the POSIX
specification: https://www.man7.org/linux/man-pages/man0/unistd.h.0p.html

This change also helps musl-libc, since they want to have these defines
with the same values as glibc.

I tried to add them for the bits/confname.h and
conform/data/unistd.h-data files following the example of the other
values, but didn't know how to plug them into the confstr / __sysconf
implementations.
