[PATCH libgpg-error] build: Restore support for cross building to musl targets.

[Érico Nogueira]

From: Érico Nogueira <erico.erc at gmail.com>

* configure.ac: Loosen the condition of using gen-lock-obj.sh for
  Linux. Commit 1fb90a7da186ee2ee098a666f6f3a35bb1720e59 tightened this
  check, but the objdump+awk trick used here works with musl toolchains
  as well as it does with glibc ones. Furthermore, uClibc targets that
  have pthreads available can also take advantage of it.
