sparc: vdso: fix build error of vdso32
Since commit 54b8ae66ae1a ("kbuild: change *FLAGS_<basetarget>.o to
take the path relative to $(obj)"), sparc allmodconfig fails to build
as follows:
CC arch/sparc/vdso/vdso32/vclock_gettime.o
unrecognized e_machine 18 arch/sparc/vdso/vdso32/vclock_gettime.o
arch/sparc/vdso/vdso32/vclock_gettime.o: failed
The cause of the breakage is that -pg flag not being dropped.
The vdso32 files are located in the vdso32/ subdirectory, but I missed
to update the Makefile.
I removed the meaningless CFLAGS_REMOVE_vdso-note.o since it is only
effective for C file.
vdso-note.o is compiled from assembly file:
arch/sparc/vdso/vdso-note.S
arch/sparc/vdso/vdso32/vdso-note.S
Fixes: 54b8ae66ae1a ("kbuild: change *FLAGS_<basetarget>.o to take the path relative to $(obj)")
