[PATCH] uml: gcc 2.95 fix and Makefile cleanup

1) Cleanup an ugly hyper-nested code in Makefile (now only the arith.
   expression is passed through the host bash).

2) Fix a problem with GCC 2.95: according to a report from Raphael Bossek,
   .remap_data : { arch/um/sys-SUBARCH/unmap_fin.o (.data .bss) } is expanded
   into: .remap_data : { arch/um/sys-i386 /unmap_fin.o (.data .bss) }

(because I didn't use ## to join the two tokens), thus stopping linking.  Pass
the whole path from the Makefile as a simple and nice fix.
