[JGIT PATCH] Repair make_jgit.sh to work in MSYS environment

[Christian Halstrick <christian.halstrick@gmail.com>]

From: Christian Halstrick <christian.halstrick@sap.com>

My MSYS installation sets the environment variable MSYSTEM to
"MINGW32" which was not handled in make_jgit.sh. Corrected that.
Also Suns Windows javac doesn't like classpathes with
/<driveletter/<dir>. When using `pwd -W` i get pathes accepted
by windows javac.
