FWIW, configure is already checking to see whether the compiler is gcc or not. There's an if clause in the configure scripts for ogg, vorbis, theora, and other of our packages that uses this to add

XIPH_C_COMPILER_IS_CLANG in configury (commit a6a4b6f) is blocking many flags including the visibility attributes: I guess this needs relaxing, possibly a lot. What incompatibility led to this commit? -- O.S.

The following patches shave some rough edges off the tools build system to allow cross compiling for at least arm32 and arm64 based on the Debian/Ubuntu multiarch infrastructure. They also add the necessary fixes to build for arm64 (which I have only tried cross, not native). I have posted some instructions on how to compile with these patches on the wiki:

Sorry I forgot to mention I didn't make any changes to the configure script. The problem is that I can't test these things since I'm not on a Unix platform, and I'm not even using the
