build fails on Linux/sparc (genprimopcode: parse error at)

Build fails when building ghc 6.4.x (tested 6.4 and 6.4.1) on Linux/
sparc and using ghc 6.4 binaries for bootstrap:

mkdir stage1/ndpFlatten
mkdir stage1/iface
mkdir stage1/cmm
mkdir stage1/ghci
Creating main/Config.hs ...
done.
Creating stage1/ghc_boot_platform.h...
Done.

The same problem doesn't exists when using ghc 6.2.x for 
bootstrapping (generated primops.txt is the same in both cases, 
tested via md5sum). Problem doesn't exists on other arch like x86, 
ppc, amd64,  too.
