I did a cvsup to -current last night and started up a buildworld.  That
succeeded.  From the log file I got from the build the output for the
file you list above came out as:

cc -O -pipe -I. -static -DGENERATOR_FILE -DTARGET_CPU_DEFAULT=TARGET_CPU_ultrasparc -DIN_GCC -DHAVE_CONFIG_H -DPREFIX=\"/usr\" -I/usr/obj/usr/src/gnu/usr.bin/cc/cc_tools/../cc_tools -I/usr/src/gnu/usr.bin/cc/cc_tools/../cc_tools -I/usr/src/gnu/usr.bin/cc/cc_tools/../../../../contrib/gcc -I/usr/src/gnu/usr.bin/cc/cc_tools/../../../../contrib/gcc/config  -I/usr/obj/usr/src/sparc64/legacy/usr/include -c /usr/src/gnu/usr.bin/cc/cc_tools/../../../../contrib/gcc/gencheck.c

Yours has an extra "-mcpu=ultrasparc", that is the only difference I
see.  Is there anything in your environment (environment variables,
or maybe something in /etc/make.conf) that might account for where that
is coming from?  Or was the run you got this message from one where
you had tried setting environment variables yourself?
