Subject: Don't try to build the icons when cross-compiling.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=e763b9ead86df6a92666525f8d2ed0385e251c61;p=sgt-puzzles.git

Don't try to build the icons when cross-compiling.

The puzzle icons are built by compiling and running a preliminary
set of puzzle binaries. We can't do that if the binaries won't run
on the build host.
