Subject: [PATCH] src/libsysprof/elfparser.h: define NT_GNU_BUILD_ID

On uclibc elf.h does not have GNU extentions but we need this define
so we define it locally if its not getting it from elf.h

It should be noted that uclibc-ng defines NT_GNU_BUILD_ID since its
version 1.0.28 and
https://github.com/wbx-github/uclibc-ng/commit/df350133f24e6202c4eaf57a1941aa2836f258ae

As a result, this patch is still needed with uclibc-ng < 1.0.28
