[ARM] 3761/1: fix armv4t breakage after adding thumb interworking to userspace helpers

Browse Source 
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 ba9b5d7637 introduced the use of
bx in the kernel, which means we need to compile with -march=armv4t on
armv4t systems now.
