MFH: r467716

Fix arm-none-eabi-gcc/aarch64-none-elf-gcc plist after r466699

jhb fixed these ports in r466699, but include-fixed headers has changed
since the last update, perhaps due to --sysroot and these ports being built
differently since then.

Add the extra headers to the plist and bump PORTREVISION due to package
differences. This fixes some sanity checking in the plist, since these files
are installed to the stage dir.
