Fix dynamic linking on Arch Linux by adding (some of) missing links.
The ldd reports linker in many ways:
ldd /usr/lib/libreadline.so.8
/usr/lib64/ld-linux-x86-64.so.2 (0x000071244211c000)
ldd /bin/sh
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2
(0x000077457d5ec000)
ldd /usr/lib/libc.so.6
/usr/lib/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2
(0x000075d218b8b000)
This patch looks at the left side and determines if there is a link
there, then adds it.
