I ended up using the '--binary' flag, but the libjxr patches still need
to be converted to DOS format to function properly. The current
procedure to get this patch running is:

$ git am 0001-gnu-Add-libjxr.patch
[whitespace complaints]
$ sed -i -e 's/\r*$/\r/' gnu/packages/patches/libjxr-fix-*
$ ./pre-inst-env guix build libjxr

The DOS formatting issue also keeps me from using 'substitute*' to patch
the Makefile to build both a shared and static version of the library.
The current package only builds a static version. Everything seems to
link properly for now, but I don't know if that will be required in the
future.
