pdf2svg: Fix Poppler dependency and download URL

Three changes:

- Download URL corrected.

- Now depends on pkg-config. Also depends on Cairo as poppler-glib requires
Cairo > 1.10, OS X 10.6.7 provides 1.8.6, and pkg-config needs the keg-only
formula to be on the PKG_CONFIG_PATH.

- Tests to see if Poppler was built with Glib support and offers a helpful
error message if this backend is missing.

Poppler: Actually depend on Glib if requested

When `--with-glib` is passed to the Poppler formula, then glib should be added
to the dependency list.

This patch also changes the way dependencies are specified to `configure` so
that it will fail if something this derpy happens again.

premake: fix Lion build

Uses an inreplace to remove "-lstdc++-static" from the makefile used for
building on Mac OS X, allowing builds to succeed on Lion. Necessary because Lion
doesn't include the stdc++-static library.
