dev-libs/opencl-icd-loader: build with -fno-common / gcc-10

Just force -fcommon in CFLAGS if tests are enabled (loader code hasn't
got any problems with -fno-common) until the next release, the problem has
already been fixed upstream but the patch is rather large.

Closes: https://bugs.gentoo.org/716410
