    Cygwin: define OUTPUT_FORMAT and SEARCH_DIR for AArch64
    
    This patch defines binutils output binary format for AArch64 which is pei-aarch64-little.
    
    Since =/usr/lib/w32api resolves to $SYSROOT/usr/lib/w32api and Fedora cross-build takes libraries from
    /usr/aarch64-pc-cygwin/sys-root/usr/lib/w32api, the SEARCH_DIR("/usr/x86_64-pc-cygwin/lib/w32api"); is
    redundant and can be removed.
