This patch adds the standard workaround (copying over the system package to $SAGE_LOCAL/lib). This should not ever fail since readline is in the base repository, and so should be installed in all systems.
Originally I thought it was because readline linked to termcap, which is disabled in Arch, but linking to curses did not help.

I've also added double quotes around almost all variable references (otherwise, there will be issues if there are spaces in the path to $SAGE_LOCAL, etc.)

I've merge http://sage.math.washington.edu/home/mhansen/readline-6.0.p1.spkg which has these changes applied on top of the ones at #7164.

Replying to timdumol:
On running Sage or the next build, readline fails with:
bash: symbol lookup error: /opt/sage-bin/local/lib/libreadline.so.6: undefined symbol: PC
This is because our shared libreadline lacks a DT_NEEDED tag for libtermcap, libncurses, libtinfo or whichever library provides these symbols (depends on the OS / distro).
I have a readline 6.2.p2 spkg which fixes this, but haven't yet opened a ticket for it...
(Just in case someone searches for this error and ends up here.)
Adds Arch Linux workaround (copies over system library)
