Did you see the following note from
http://www.kegel.com/crosstool/crosstool-0.42/doc/crosstool-howto.html:


Crosstool, and probably gcc and glibc's configure scripts, assume that 
directory names do not contain any spaces. This is often violated on 
Windows. Please take care to not use directory names with spaces in them 
when running crosstool. It might work, but if it doesn't, you've been 
warned. (Same goes for Mac OS X.)

crosstool creates some really deeply nested directories while building, so 
filenames are quite long. This has two consequences:

First, on some versions of Windows, filenames (including directory) can't be 
longer than 240 chars. To avoid exceeding this limit, don't run crosstool in 
a directory with a long name.

Second, the maximum length of commandlines is extremely short. Since 
crosstool uses commandlines that include multiple filenames, they can exceed 
the limit very quickly. You can avoid this problem by using the "mount" 
command's options. e.g. mount /bin and /usr/bin with -X or "-o cygexec" (see 
the cygwin faq, and/or mount the crosstool directory with "-o managed" (see 
the cygwin doc for "mount").


It's easy to run afoul of either of these two.

HTH,
