[v4l-utils,v1,1/2] v4l2-tracer: wrap open64/mmap64 functions only if linux && __GLIBC__
Commit Message
Wrap open64/mmap64 functions only if linux && __GLIBC__, as done
in lib/libv4l1/v4l1comapt.c and lib/libv4l2/v4l2convert.c since
commit 'libv4l: Wrap LFS64 functions only if linux && __GLIBC__'
(403a4e2697a1ff96fe2fa16589039595f21cadf0), should fix musl libc
compile.
