aarch64: fix check for SVE support in assembler
Due to GCC bug 110901 -mcpu can override -march setting when compiling asm code and thus a compiler targetting a specific cpu can fail the configure check even when binutils gas supports SVE. The workaround is that explicit .arch directive overrides both -mcpu and -march, and since that's what the actual SVE memcpy uses the configure check should use that too even if the GCC issue is fixed independently. Reviewed-by: Florian Weimer <fweimer@redhat.com> (cherry picked from commit 73c26018ed0ecd9c807bb363cc2c2ab4aca66a82)
