Use BLX instead of "MOV pc" function calls.
The new patch uses BLX all the time, and thus imposes an ARMv5T baseline requirement for XPCOM. (We previously had this requirement for the JIT anyway, but that could be trivially disabled for crazy people who wanted to compile for ARMv4.)
I've (barely) tested this with the ARM build, but couldn't get GCC 4.3.3 to produce a Thumb-2 build. (The error looked like a compiler error in an unrelated module.) I could massage it into building just the bits we care about with -mthumb, but it takes a long time to build anyway, let alone with me hacking the build system.
In any case, I've delayed enough for such a trivial patch, so here it is. Whilst it's trivial, it wants pushing to the try server or something like that before it's actually pushed.
