arm: workaround to build Cortex-M7 targets with GCC 4.9

Browse source 
Cortex-M7 support was added in GCC 5, while GCC 4.9 only
supports the M4. The instruction set is almost identical
between both processors; the only difference is that the
M7 supports double-precision floating point and the M4
doesn't.

Since Rockbox currently doesn't use the FPU, building M7
targets as M4 works fine.
