Strange `find` syntax error in crosstool-ng

[Michael Abbott]

My crosstool build fails with the message

[INFO ]  Installing final compiler: done in 520.97s
[38:16] / find: missing argument to `-exec'
[ERROR]  Build failed in step "<none>"
[ERROR]  Error happened in "/scratch/crosstool-ng-1.0.0/scripts/crosstool.sh" in function "main" (line unknown, sorry)

and the error is clearly due to lines 400-402 in crosstool.sh which are of 
the form
 	find ... -name ... -exec rm -fv {} \+ | CT_DoLog DEBUG

Eh?  How on earth did \; become transformed into \+?  This is in both the 
1.0.0 tar bundle and the svn version (which seem to be identical apart 
from the .version file).

The attached patch should fix this, but I haven't tested it yet.
