Recent change to GCC may require changing Glibc tests

[Yury Khrustalev]

Hi all,

I wonder what do you think about this issue?
https://sourceware.org/bugzilla/show_bug.cgi?id=32366

This is related to recent commit to GCC trunk:
7828dc07051 Remove allocations which are used only for NULL pointer check and free

Building tests with either -fno-malloc-dce or -fno-builtin-malloc didn't work. The
former (a new GCC option) results in further compilation errors and with the latter
tests compile but some of them still fail (although number of failures is reduced).

Kind regards,
Yury
