build: work around ubuntu focal gcc-9 arm cross issue
Ubuntu's libgcc-9-dev-arm64-cross on focal is broken: it misses
patch 8c92fcb13a4979232787f0476bf7469ccbb03617 that fixes a
mismatched "extern C" block in arm_acle.h.

We provide the patched header file in src/compat and include a
selector for it. Whenever we detect GCC 9.4, we include the
imported header rather than the system provided, broken header.

This patch can be reverted when Ubuntu has fixed
libgcc-9-dev-arm64-cross.
