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.
