LIBARCHNAME in CompileLauncher.gmk

[Jeremy Manson]

LIBARCHNAME as defined in CompileLauncher.gmk seems to be i586 in 32-bit
x86 instead of being i386.  It's using the wrong make variable.

LIBARCHNAME doesn't happen to be used in any of the launchers, so it hasn't
caused a problem, but it should probably be either fixed or removed.
 Here's a patch to fix it (I'm biased towards this, because our launcher
changes use it, but I could certainly understand going the other way).
