powerpc/vdso: Don't discard rela sections

Browse Source 
[ Upstream commit 6114139c3b ]

After building the VDSO, there is a verification that it contains
no dynamic relocation, see commit aff69273af ("vdso: Improve
cmd_vdso_check to check all dynamic relocations").

This verification uses readelf -r and doesn't work if rela sections
are discarded.

Fixes: 8ad57add77 ("powerpc/build: vdso linker warning for orphan sections")
