catch is ancient and has no support for aarch64-darwin. The following
snippet is an example of what is supported on darwin platforms in catch
(i.e., prior to v2).
```
#ifdef CATCH_PLATFORM_MAC
#if defined(__ppc64__) || defined(__ppc__)
#define CATCH_TRAP() \
__asm__("li r0, 20\nsc\nnop\nli r0, 37\nli r4, 2\nsc\nnop\n" \
: : : "memory","r0","r3","r4" ) /* NOLINT */
#else
#define CATCH_TRAP() __asm__("int $3\n" : : /* NOLINT */ )
#endif
```
Fix wrong header for statfs function.
Use gccStdenv to build with GCC on all systems. GCC is hardcoded in
configure.in, but after setting CC_FOR_BUILD to cc to use Clang, the
build fails anyway when running a post-compilation command:

Also build from source instead of using the binaries.
We cannot (yet) build the fully optimized version as it requires the
ASMC assembler which currently doesn't build with GCC.

Fix it by using `gzip -n`.
