powerpc/vdso: Fix build of VDSO32 with pcrel
Building vdso32 on power10 with pcrel leads to following errors:
VDSO32A arch/powerpc/kernel/vdso/gettimeofday-32.o
arch/powerpc/kernel/vdso/gettimeofday.S: Assembler messages:
arch/powerpc/kernel/vdso/gettimeofday.S:40: Error: syntax error; found `@', expected `,'
arch/powerpc/kernel/vdso/gettimeofday.S:71: Info: macro invoked from here
arch/powerpc/kernel/vdso/gettimeofday.S:40: Error: junk at end of line: `@notoc'
arch/powerpc/kernel/vdso/gettimeofday.S:71: Info: macro invoked from here
...
make[2]: *** [arch/powerpc/kernel/vdso/Makefile:85: arch/powerpc/kernel/vdso/gettimeofday-32.o] Error 1
make[1]: *** [arch/powerpc/Makefile:388: vdso_prepare] Error 2
Once the above is fixed, the following happens:
VDSO32C arch/powerpc/kernel/vdso/vgettimeofday-32.o
cc1: error: '-mpcrel' requires '-mcmodel=medium'
make[2]: *** [arch/powerpc/kernel/vdso/Makefile:89: arch/powerpc/kernel/vdso/vgettimeofday-32.o] Error 1
make[1]: *** [arch/powerpc/Makefile:388: vdso_prepare] Error 2
make: *** [Makefile:251: __sub-make] Error 2
Make sure pcrel version of CFUNC() macro is used only for powerpc64
builds and remove -mpcrel for powerpc32 builds.
