elfutils-0.187 failing to build for a MUSL MIPS target

[Immolo <immoloism@googlemail.com>]

Hi,

When trying to cross compile elfutils-0.187 for a MIPS device it fails with
various errors depending on the USE flags set on my crossdev Gentoo setup.

I believe but have not confirmed this is a MIPS issue until I have done
further tests.

in the MUSL overlay also fails with the same issue so I need to run some
 further tests on other arches.


With USE="bzip2 nls threads utils" I get a numbe of undefined variables
with the final error "being undefined reference to `assert_perror'"

With USE="-*" then it becomes:

 213 |       if (fnmatch (pattern->pattern, name, FNM_EXTMATCH) == 0)
      |                                            ^~~~~~~~~~~~
      |                                            FNM_NOMATCH

      |                                     FNM_NOMATCH

fI'll include the build logs for both below but I would be grateful if
anyone has any ideas on how I can start to solve this isse.
