Subject[PATCH] sparc: vdso: fix build error of vdso32
Date
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.

Fixes: 54b8ae66ae1a ("kbuild: change *FLAGS_<basetarget>.o to take the path relative to $(obj)")
