The GCC ebuilds all use toolchain.eclass which is incomprehensible to |
| 8 |
me, but it looks like the default behavior for gcc-6.x is to pass |
| 9 |
"--enable-default-pie" and "--enable-default-ssp" to the build process |
| 10 |
of GCC itself. That changes the default behavior of GCC to (as the names |
| 11 |
say) enable PIE and SSP by default. |

Consequently, if a package ignores your CFLAGS, the PIE/SSP should still |
| 14 |
take effect, because GCC does them by default. Only a package that adds |
| 15 |
its own -no-pie flag (for example) would cause problems. |
