Unfortunately, this broke Solaris bootstrap:

/usr/include/sys/ustat.h:31:2: error: #error "Cannot use ustat in the large files compilation environment"
make[4]: *** No rule to make target `s-sysinfo', needed by `sysinfo.go'.  Stop.
make[4]: *** Waiting for unfinished jobs....

<sys/ustat.h> has

#if !defined(_LP64) && _FILE_OFFSET_BITS == 64
#error	"Cannot use ustat in the large files compilation environment"
#endif

I've used the hack below to restore bootstrap, but suppose a cleaner
solution would be to run the configure tests with the same flags as used
for the actual compilations (i.e. OSCFLAGS).

Alternatively, one could restrict the use of <ustat.h> to Linux since
it's only used in go/syscall/libcall_linux.go anyway.
