[PATCH v2 0/2] Prepare our git-p4 tests for running on APFS

Yesterday, the macOS agents of Azure Pipelines were upgraded to Mojave, and since that does not support HFS+ anymore, everything will be upgraded to APFS.

As I just found yesterday, we have one test that fails on that filesystem (t9822, which is only run if Perforce's p4d is available).

The first patch adds a workaround, as I failed to find any way to finagle APFS into accepting that ISO-8859-1 encoded file name.

The second patch is a fix to make things compile on Mojave again, apparently Homebrew changed and the /usr/local/ directories need to be added to the compiler and linker flags explicitly. Maybe this is a gcc-8 only thing, as it seems to have affected only the osx-gcc job, not the osx-clang job.

Changes since v1:

 * Fix the tyop in the oneline of the first patch where it should talk about
   ISO-8859-1.

          Most notably, it seems that macOS' APFS does not allow that.
