Felix Fietkau 61eee1adfb toolchain/gcc: switch to version 7 by default
Newer GCC versions are reported to improve code size on various ARM
devices, which is why newer u-boot versions require them now.
There have also been user reports of data corruption issues fixed on
MIPS by updating from GCC 5 to GCC 7.

This update was previously held up by these two MIPS compile issues,
which have since been fixed:
