Removed commands for building libcurl from makefile.unix. It should be installed seperately.
Added a necessary directory, compile will fail if it is not created. Added a dummy file to it so git will commit it.
Removed workaround for ancient GCC bug. If you're using a version that old, you should expect bugs. No reason to clutter the makefile.
