flac: fix benchmark linking issue with older glibc versions
Fixes: http://autobuild.buildroot.net/results/b64/b643824d797050d7c001a3b72598158d8f1c6128/ http://autobuild.buildroot.net/results/a2f/a2f2d7b4e9e7b57bc8691e3ec29ecf818be3f79b/ The benchmark tool uses clock_gettime which is available in librt instead of libc in older glibc versions. The build system correctly links with -lrt on Linux systems, but misdetects non-x86 linux systems as !linux, causing build failures. Add a patch to relax the linux OS detection to also work on non-x86 systems.

Subject: [PATCH] configure.ac: relax linux OS detection
|
||||
|
||||
Not all linux hosts match the *-pc-linux-gnu wildcard, causing build
|
||||
failures for older glibc versions where we need to link with -lrt for
|
||||
clock_gettime - E.G.:
|
||||
|
||||
- arm-unknown-linux-musleabihf
|
||||
- powerpc-unknown-linux-gnuspe
|
||||
- bfin-linux-linux-uclibc
