Prevent default-fPIE from confusing configure into thinking
|
|
PIC code is default. This causes glibc to build both PIC and
|
|
non-PIC code as normal, which on the hardened compiler generates
|
|
PIC and PIE.
|
|
|
|
Patch by Kevin F. Quinn <kevquinn@gentoo.org>
|
|
Fixed for glibc 2.19 by Magnus Granberg <zorry@ume.nu>
