The leading - makes it rather inconsistent with the majority of other
projects around the world. Use the form everyone else uses.
To solve this, properly pass prefix to inner makes as was always
intended.

Sampling time and sequence length, along with the vbat channel are
specific to the f4/f7, and can't be shared with the l1 and friends.
Pull them out to their own common file.
the 2014q3 or later toolchains are now readily available, and we should
now just consider this a user problem. This gets us out of trying to
parse compiler help output and chasing our own tail.

This shows what is _actually_ different for f7. A couple of option
bits, and a renaming of bit 7 of the status register, from Program
Sequence Error to Erase Sequence Error.
We keep the separate implementation of wait_for_last_operation, to meet
the "suggestions" of the reference manual to insert a DSB instruction.
Keeping the renamed bit/functions also requires us to keep separate
implementations of the flag clearing functions
Turns out, there's lots of common code for flash. Pull up prefetch
on/off to start with, as there's only a single bit name different.
Pull up the definitions of common API functions too, starting with
flash_set_ws. Even if the implementations are different, things that
meant to be the same, should be defined centrally.
Add clock config for the 25MHz crystal found on the discovery board.
Verified to work on the STM32F7-Disco.

3a7cbec7: stm32l/stm32f: name space standardization [BREAKING]
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.
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.
