Pass CFLAGS_FOR_TARGET to the newlib libgcc/libc builds

lets us do things like target the medany code model.

Move GCC to the 7 release branch
GCC has created a stable branch upstream for the 7 release series. This
patch moves our GCC sources over to that branch, just like we did for
binutils.

Improve error message for unavailable newlib multilibs ( #214 )
For some reason, a Newlib multilib build includes a "default" library
in addition to the multilibs ones. This results in confounding error
messages when an invalid multilib is requested on the GCC command line.
Now, it reports a more sensible "cannot find -lc".

Fix interaction of -mno-float with -march
10 years ago
a1e7a925c1
Overhaul floating-point command-line arguments
- -march controls which instructions may be emitted, and does not
affect ABI.
- -mno-float is equivalent to passing neither F for D to -march;
-msingle-float is equivalent to passing F but not D to -march;
and -mdouble-float is equivalent to passing F and D to -march.
- -mfloat-abi controls which calling convention is used: "soft" means
no args passed in registers; "single" means only single-precision
values are passed in regisers; "double" means single- and
double-precision values are passed in registers.
- -mfloat-abi defaults to "soft" if the D extension is not present,
or "double" if it is.
- GCC will issue an error if -mfloat-abi requires an extension not
provided by -march, but vice-versa is OK.
Closes #187 (I hope).
@kito-cheng can you test this and let me know what I need to fix?
