The js package is 6.5MB.
BTW I suppose that could be significantly reduced by linking /usr/bin/js
with the dynamic libmozjs instead of the static one generated during the
build. It seems to take something more than just the attached patch though.
Most interpreters deliberately do this because non-PIC code is
significantly faster than PIC code, especially on architectures without
IP-relative addressing. These days, it may be possible to recover some
of the lost performance by tweaking ELF symbol visibility or
amalgamation builds (that is, stuffing everything in a single C file;
-flto could perhaps provide an equivalent).
