Subject: [PATCH] src/internal: Use __GLIBC__ to check for GNU extention
implementation
__USE_GNU is defined by _GNU_SOURCE and configure explicitly sets this
macro and it does have meaning on musl too, where it may have some level
of GNU compatibility but strerror_r is not one of them. Therefore we
have to check for libc implementation for this to be sure.
