crosstool-ng/packages/gcc/7.3.0/0002-gcc-plugin-Win-Dont-need-undefined-extern-var-refs-nor-fpic.patch
Alexey Neyman 36bb675a71 More fixes after the upgrades:
- 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.
