cleanup arch/alpha/Makefile
- binutils 2.7 is far below the current minimum supported version, and there's therefore no longer a need for an extra test - since even gcc 3.2 already supports all options used we can use them unconditionally Signed-off-by: Adrian Bunk <bunk@stusta.de> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
