Using multiple versions of GCC in the same package is poorly supported
since the recent 'core-updates' merge, causing these obscure errors.

The actual problem with FreeHDL is that it assumes std::string,
std::hash, etc is available in the default namespace, which is why it
was built with GCC 5 instead of the default GCC 7.  I found a patch over
at Arch that makes it work with newer versions of GCC and C++:

https://git.archlinux.org/svntogit/community.git/tree/trunk/build-fix.patch?h=packages/freehdl

I applied it to our package with commit
1a044e3936ac4c1ba1575fe791bf59577b039cf9 and removed the GCC 5 input.
