Bug#794994: graphite2: FTBFS on !linux archs

[Pino Toscano <pino@debian.org>]

Source: graphite2
Version: 1.3.0-1
Severity: important
Tags: patch

Hi,

graphite2 1.3.0-1 fails to build on kFreeBSD [1][2] and Hurd [3].

The problem is that tests/graphite.py does not have any library item
for these platforms registered in the grfiles dictionary, so the script
will fail with a KeyError exception.

The fix, which is suitable for upstream (so please do forward it),
is to slightly rework the logic for knowing the library name on the
current platform: since there will be far more platforms with the name
libgraphite2.so (Linux, kFreeBSD, Hurd, and any other BSD platform for
sure), then fallback to that name for missing items in the grfiles
dictionary. Hence, that dictionary contains now only platforms where
the library name is not libgraphite2.so, and the linux2 mapping is no
more needed.
Patch attached for this.
