+ gcc and GNU make to generate dependencies.

--enable-profiling build emacs with profiling support. This might not
work on all platforms
+ --enable-autodepend automatically generate dependencies to .h-files.
+ Requires GNU Make and Gcc. Enabled if GNU Make and
+ Gcc is found
--disable-largefile omit support for large files
