>Description:

The www/firefox52 package has been switched to use its internal ICU library.
This change broke the pkg at runtime for big endian machines.

The problem is the hard coded ICU_DATA_FILE, see

build/autoconf/icu.m4:

    MOZ_ICU_VERSION="$version"
    
    # TODO: the l is actually endian-dependent
    # We could make this set as 'l' or 'b' for little or big, respectively,
    # but we'd need to check in a big-endian version of the file.
    ICU_DATA_FILE="icudt${version}l.dat"

So we would need to add a icudt58b.dat after extraction and make that
line depend on endianess. We also probably will need a PLIST variable for
this.

>How-To-Repeat:

Try to start firefox52 on any big endian machine.
