    gnu: gcc-boot0: Enable 128-bit long double for POWER9.
    
    * gnu/packages/commencement.scm (gcc-boot0) [#:configure-flags]: Add
    --with-long-double-128 when the boot triplet is 
"powerpc64le-guix-linux-gnu",
    instead of "powerpc64le-linux-gnu", which is incorrect.  The actual triplet
    used during bootstrapping is "powerpc64le-guix-linux-gnu".
