Patch for libstdc++ bootstrap on sparc-sun-solaris2.6

[Branko]

It seems there were some bits missing in the config files for Solaris 
2.6. With the attached patch, I can bootstrap current CVS and pass the 
testsuite 166/16, using binutils 2.10.1.

	* config/os/solaris/solaris2.6/bits/os_defines.h: Define
	_XOPEN_SOURCE, _LARGEFILE64_SOURCE, __EXTENSIONS__, __off_t,
	__off64_t and __ssize_t.
