Failed to build emacs against imagemagick 6.8.4.6

[YE Qianchuan]

Hi, all. I'm on Archlinux x86_64.
It kept complaining about undefined reference to <imagemagick symbol>.
Since I built it smoothly before upgrading imagemagick to 6.8.4.6, I 
guess it's an incompatibility issue.

A sample error output is as follows:

../lib-src/make-docfile -a ../etc/DOC -d <my emacs src dir>/src/../lisp 
`sed -n -e 's| \\\\||' -e 's|^[ ]*$(lispsource)/||p' <my emacs src 
dir>/src/lisp.mk`
