[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 ba9b5d76 introduced the use of bx in the kernel, which means we need to compile with -march=armv4t on armv4t systems now.
