[arm-gnu] Problem compiling zlib

["s premi" <sanjeev.premi@xxxxxxxxx>]

While trying to build zlib1.2.3 (using 2008-q1) I come across this error:

arm-none-linux-gnueabi-ar libz.a adler32.o compress.o crc32.o gzio.o
uncompr.o deflate.o trees.o zutil.o inflate.o infback.o inftrees.o

make: *** [libz.a] Error 1

But, when I see the command-line there is no option "z".

Any clues to get the build succeed?
