- GLIBC requires a fix to work with binutils 2.30 on aarch64. This fix
relies on binutils 2.24 or newer, which is okay for glibc 2.26 since
it needs 2.25 or newer anyway. But older glibc versions are now pinned
to binutils 2.29 or older on aarch64.
- xtensa needs patches in libgcc with gcc 7.3.
- comment in newlib's patch to indicate it is a reversal of a commit.
