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
