much of an issue.

Shouldn't this be in the ebuilds? eg.

Since an update to the default USE flags on gcc 6 turned on PIE and SSP,
i'm getting these errors;
/usr/lib/gcc/x86_64-pc-linux-gnu/6.3.0/../../../../x86_64-pc-linux-gnu/bin/ld:
atof-generic.o: relocation R_X86_64_32 against `.rodata' can not be used
when making a shared object; recompile with -fP
