Fix handling of GNU Property notes that are not in a GNU NOTE PROPERTY section.
PR 22450
gas * elf-properties.c (_bfd_elf_link_setup_gnu_properties): Skip
objects without a GNU_PROPERTY note section when looking for a bfd
onto which notes can be accumulated.
ld * testsuite/ld-elf/elf.exp: Add --defsym ALIGN=2|3 to assembler
command line depending upon the size of the target address space.
* testsuite/ld-elf/pr22450.s: New test file.
* testsuite/ld-elf/pr22450.d: New test driver.
* testsuite/config/default.exp: Add note that LD_CLASS refers to
the size of the host linker not the size of the target linker.
