perf tools: Fix up build in hardnened environments
On Fedora systems the perl and python CFLAGS/LDFLAGS include the
hardened specs from redhat-rpm-config package. We apply them only for
perl/python objects, which makes them not compatible with the rest of
the objects and the build fails with:
/usr/bin/ld: perf-in.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -f
+PIC
/usr/bin/ld: libperf.a(libperf-in.o): relocation R_X86_64_32S against `.text' can not be used when making a shared object; recompile w
+ith -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile.perf:507: perf] Error 1
make[1]: *** [Makefile.perf:210: sub-make] Error 2
make: *** [Makefile:69: all] Error 2
Mainly it's caused by perl/python objects being compiled with:
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1
which prevent the final link impossible, because it will check
for 'proper' objects with following option:
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld
