[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.
