Well, this is the same for x86_64.

$ grep -rl '\<REG_EAX\>' /usr/include/
/usr/include/x86_64-linux-gnu/sys/ucontext.h

$ ls -l /usr/include/sys/ucontext.h
lrwxrwxrwx 1 root root 34 Feb 22 12:45 /usr/include/sys/ucontext.h ->
../x86_64-linux-gnu/sys/ucontext.h

So I am not sure I understand why we redefine stuff already available from
the toolchain.
Rather than prefixing, I think we should get rid of this and include the
right header.
