Something is wrong with the packaging of the Font Awesome fonts in the
fontawesome-fonts-4.6.3-10.1.noarch package (in the M17N repository).  When the
fonts are installed from this package, xelatex fails to detect them, and issues
an error message when any document using them is compiled.

However, when the same Font Awesome fonts are installed manually (say, by
downloading them from
<https://github.com/FortAwesome/Font-Awesome/archive/v4.6.3.tar.gz> and
installing them as root with kfontinst), xelatex has no problem finding and
using the font.

Steps to reproduce:

$ sudo zypper in fontawesome-fonts-4.6.3-10.1.noarch
$ cat >foo.tex
\documentclass{article}
\usepackage{fontawesome}
\begin{document}
\faAsterisk
\end{document}
$ xelatex foo.tex

Observed behaviour:

xelatex fails with the following error message:

xdvipdfmx:fatal: Cannot proceed without the font:
/usr/share/fonts/truetype/fontawesome-webfont.woff

Expected behaviour:

xelatex should have compiled foo.tex without any errors.
