>Description:
I configured a Sparc profiling kernel with "config -p GENERIC"
During the build, genassym would not build with the following error:
	cc -o genassym genassym.o
	ld: genassym.o: RRS text relocation at 0x2a60 for "mcount"
	ld: genassym.o: RRS text relocation at 0x2ab0 for "mcount"
	ld: genassym.o: RRS text relocation at 0x2e5c for "mcount"
	./genassym >assym.h
	Segmentation fault
	*** Error code 139

	Stop.
I copied a genassym from a non-profiling build and managed to get a working
assym.h. Then I ran into this problem:

cc  -O2 -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -I. -I../../../../arch -I../../../.. -DGPROF -DSUN4 -DSUN4C -DSUN4M -DSWAPPAGER -DVNODEPAGER -DDEVPAGER -DKTRACE -DSYSVMSG -DSYSVSEM -DSYSVSHM -DLKM -DCOMPAT_43 -DCOMPAT_10 -DCOMPAT_11 -DCOMPAT_SUNOS -DCOMPAT_SVR4 -DFFS -DQUOTA -DNFSSERVER -DNFSCLIENT -DKERNFS -DNULLFS -DMFS -DFDESC -DUMAPFS -DLFS -DPORTAL -DPROCFS -DCD9660 -DUNION -DFIFO -DINET -DTCP_COMPAT_42 -DRASTERCONSOLE -D_KERNEL -pg -c ../../../../kern/kern_clock.c
cc1: warnings being treated as errors
machine/profile.h:69: warning: `_mcount' declared `static' but never defined
*** Error code 1

Stop.

I fixed this by removing the "static" specifier in the declaration of 
_MCOUNT_DECL in sparc/include/profile.h. But I seem to remember this caused
some problem in building libc. 

>How-To-Repeat:
cd /sys/arch/sparc/conf
config -p GENERIC
cd ../compile/GENERIC
make
*boom*

>Fix:
The second problem can be fixed by removing "static" in profile.h. But this
might cause problems elsewhere.

I have no idea what the first error message even means.
