This is a temporary fix to enable hydra to complete evaluations, which were
broken by f7ee7a9b06 due to a missing patch
file. The real patch will be put into place in a later commit.
* gnu/packages/patches/perl-gd-options-passthrough-and-fontconfig.patch:
New file. This is just a stub.
* gnu-system.am (dist_patch_DATA): Add it.
