Reported buildbot issue is:
/store/buildbot/slave/ar71xx/build/build_dir/target-mips_34kc_musl-1.1.11/ola-0.9.7/plugins/openpixelcontrol/.libs/libolaopenpixelcontrol.so: undefined reference to `ola::network::TCPSocket::ReadDescriptor() const'
collect2: error: ld returned 1 exit status

There's also a discussion (attempt) to fix this on the buildroot project:
  https://patchwork.ozlabs.org/patch/503884/

This bug has been reported (from the buildroot project), here:
  https://github.com/OpenLightingProject/ola/issues/880

This commit introduced the issue:
  bfc1d99055
specifically the `-fvisibility-inlines-hidden` switch.

So, until, the upstream project (ola) fixes this, this fix
looks like the quickest/simplest workaround to have this package build.
