description:
bootstrap: Remove old -isystem hack on macOS.

This was introduced many years ago in PR#26143 to try and work around a
misconfiguration in how Apple's GCC was built at the time.  Newer compilers no
longer look in /usr/local/include, and this workaround can now be harmful when
trying to pick a specific SDK to build against.
