7545a321b0 cortex-m7: improve compiler detection
Recent debian testing and ubuntu 15.10 releases contain a
gcc-arm-none-eabi toolchain that returns 0 for the test with -mcpu and
-fsyntax-only, despite not actually supporting cortex-m7.  They then
failed hard on actual compilation steps.

Use the --help=target output instead. tested with old g-a-e 4.7 and
newer releases.

3ef2c38120 [stm32f7] Add initial support of the family, GPIO support.
Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
