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)") Reported-by: Anatoly Pugachev <matorola@gmail.com> Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Tested-by: Anatoly Pugachev <matorola@gmail.com> Acked-by: David S.
