These patches fix some compilation / linking issues with clang & lld.
Bill Wendling (2):
powerpc/wrapper: Add "-z notext" flag to disable diagnostic
powerpc/boot: Use clang when CC is clang
arch/powerpc/boot/Makefile | 4
arch/powerpc/boot/wrapper | 6 --

The "-z notext" flag disables reporting an error if DT_TEXTREL is set.
ld.lld: error: can't create dynamic relocation R_PPC64_ADDR64 against
symbol: _start in readonly segment; recompile object files with
-fPIC or pass '-Wl,-z,notext' to allow text relocations in the
output
>>> def
Both .dynamic and .got are RELRO sections and should be placed together,
and LLD emits an error:
ld.lld: error: section: .got is not contiguous with other relro sections
Place them together to avoid this.
