x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only
relocatable objects which don't contain any instructions, linker
shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging
GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain
GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs.
This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates
readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has
the GNU_PROPERTY_X86_UINT32_VALID bit.
