    Install correct bits/long-double.h for MIPS64 (bug 22322).
    
    Similar to bug 21987 for SPARC, MIPS64 wrongly installs the ldbl-128
    version of bits/long-double.h, meaning incorrect results when using
    headers installed from a 64-bit installation for a 32-bit build.  (I
    haven't actually seen this cause build failures before its interaction
    with bits/floatn.h did so - installed headers wrongly expecting
    _Float128 to be available in a 32-bit configuration.)
    
    This patch fixes the bug by moving the MIPS header to
    sysdeps/mips/ieee754, which comes before sysdeps/ieee754/ldbl-128 in
    the sysdeps directory ordering.  (bits/floatn.h will need a similar
    fix - duplicating the ldbl-128 version for MIPS will suffice - for
    headers from a 32-bit installation to be correct for 64-bit builds.)
    
    Tested with build-many-glibcs.py (compilers build for
    mips64-linux-gnu, where there was previously a libstdc++ build failure
    as at
    <https://sourceware.org/ml/libc-testresults/2017-q4/msg00130.html>).
