#766 Merge upstream GNU binutils 2.38 into our fork

[Philipp Klaus Krause]

The last time GNU binutils was merged in our fork was at binutils 2.30. The current upstream is 2.38.

binutils tends to generate lots of warning when compiled; its a race between binutils removing warnings, and new versions of GCC / clang introducing more. The large number of warnings we see from binutils is annoying noise, merging a current upstream should help a bit with that.
