perf tools: check if -DFORTIFY_SOURCE=2 is allowed
It seems gcc (4.7.2) defines _FORTIFY_SOURCE internally and becomes
confused when it sees another definition in flags.
For me, build failed like this:
CHK glibc
Makefile:548: *** No gnu/libc-version.h found, please install glibc-dev[el]/glibc-static. Stop.
and only with V=1 it printed:
<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<stdin>:1:0: note: this is the location of the previous definition
