Makefile: Build with -D_GNU_SOURCE=1
For x86 the ucontext.h only provides the #defines for register indexes
if _GNU_SOURCE is enabled; enable it.
As part of this, split our CFLAGS into:
* CFLAGS: can be set by the user, defaults to -g
* EXTRA_CFLAGS: set by the user, additional to CFLAGS
* ALL_CFLAGS: the above, plus flags we must have in order
to build correctly (or otherwise don't want the user to disable)
