Simple work-around for running the 64-bit Adobe Flash plug-in version 10
on Athlon64 processors without support for the lahf instruction.

Compile with:
cc -fPIC -shared -nostdlib -lc -oflashplugin-lahf-fix.so flashplugin-lahf-fix.c

Then place the .so file in the plug-in directory (e.g. $HOME/.mozilla/plugins)
or use LD_PRELOAD to force Firefox to load the library.

This slackbuild will put the flashplugin-lahf-fix.so file into
/usr/lib64/mozilla/plugins directory
