Building the powerpc tests with GNU ld 2.46.1 fails when linking the
test binaries:
/usr/bin/ld.bfd: error: read-only segment has dynamic relocations
The tests are linked with -pie and relocate themselves at boot (see
relocate() in powerpc/reloc64.c, called from powerpc/cstart64.S).
Newer GNU ld rejects relocations in read-only segments by default. The
Makefile already checks after linking that only R_PPC64_RELATIVE
relocations are present.
Fix this by adding `-z notext` to the powerpc linker flags, as was done
for arm64 in commit 5d67db4e1860 ("arm64: Link with -z notext").
