| Subject: [PATCH] Fix usage of __GLIBC_PREREQ for non-glibc toolchains |
| |
| The way __GLIBC_PREREQ() is currently used means that it's evaluated |
| even if __GLIBC__ is not defined. But obviously, __GLIBC_PREREQ will |
| not exist if __GLIBC__ is not defined, causing build failures on C |
| libraries not defining __GLIBC__ such as the musl C library. |
| |
| Patch originally taken from: |
| https://github.com/voidlinux/void-packages/blob/master/srcpkgs/numactl/patches/musl.patch |
