    binutils/GCC: Quote ${COMPILER_FOR_TARGET}

    Replace

    if test x${COMPILER_FOR_TARGET} = x"\$(CC)"; then

    with

    if test x"${COMPILER_FOR_TARGET}" = x"\$(CC)"; then

    since COMPILER_FOR_TARGET may contain spaces when configuring GCC.

    Use AC_TRY_COMPILE to check for the working target clang and gcc when
    configuring for cross tools.

    binutils: Pass target plugin file to target ar/nm/ranlib

    There are 2 kinds of binutils tests:

    1. Tests of binutils object files and libraries using the build tools,
    like CC, AR, NM and RANLIB.
    2. Tests of binutils programs as the target tools, like CC_FOR_TARGET,
    AR_FOR_TARGET, NM_FOR_TARGET and RANLIB_FOR_TARGET.

    Set AR_PLUGIN_OPTION_FOR_TARGET, NM_PLUGIN_OPTION_FOR_TARGET and
    RANLIB_PLUGIN_OPTION_FOR_TARGET to the target compiler plugin file for
    target ar/nm/ranlib.

    Binutils/GCC: Add clang LTO support to AR, NM and RANLIB

    Add CLANG_PLUGIN_FILE to find the clang plugin file and pass it to
    --plugin for ar, nm and ranlib so that binutils can be built with
    clang LTO.  Run CLANG_PLUGIN_FILE before GCC_PLUGIN_OPTION since
    GCC_PLUGIN_OPTION may return the wrong PLUGIN_OPTION with clang.

    When removing Solaris/PowerPC support, I missed a couple of references.
