  execinfo.h is not supported by musl now.
need to remove references to execinfo.h to
build DPDK with musl.

musl is an implementation of the userspace portion
of the standard library functionality described in
the ISO C and POSIX standards, plus common extensions.

Get more details about musl from
http://www.musl-libc.org

This also aplies to some other LIBC implementation which
doesn't support backtrace( ) and backtrace_symbols( ).
