Musl doesn't provide a way of explicitly identifying it, so find it
implicitly as "not glibc and not uclibc".
explicitly

This is necessary to address the following error with musl C library:
error: invalid application of 'sizeof' to incomplete type
'linux_syscall_support::timespec'
This is necessary to prevent creation of conflicting function
declarations in case of musl C library.
There should be just one PT_NOTE segment in a core file.
And otherwise gdb identify such core file as corrupted.
