First things first, make sure you read the CrossGCC FAQ (Bill Gatliff's
semi-complete version) at http://billgatliff.com .

Do you need Fortran and Java support on the Sparc?  If not, add
'--enable-languages="c,c++"' (without the single quotes) to your original
configure command to build just the C and C++ compilers.

I believe boehm-gc is a garbage collector for Java, so it would be used for
the target system.
