[ARM] 3761/1: fix armv4t breakage after adding thumb interworking to userspace helpers
Patch from Lennert Buytenhek
On armv4t systems, we have always compiled the kernel with -march=armv4
instead of -march=armv4t, which means that any use of bx will bomb out.
Commit ba9b5d76372dc290b6ca04dad93927a22c2ac49a introduced the use of
bx in the kernel, which means we need to compile with -march=armv4t on
armv4t systems now.
