* libnosys/configure.in (libc_cv_asm_previous_directive): Set
        cache-id variable.
        (libc_cv_asm_popsection_directive): Ditto.
        (libc_cv_section_attributes): Ditto.
        (libc_symbol_prefix): Rename from libc_dollar_prefix.  Check for
        "_" as well, and set __SYMBOL_PREFIX accordingly.
        * libnosys/configure: Regenerate.
