* Description
MIT/GNU Scheme tarball provides two subdirectories, `src' and `doc', each with
its own makefile. The default PKGBUILD only builds `src', meaning the manpage
and the info files don't make it into the package.

In addition, even though the build is configured with `--with-x', the X11 plugin
doesn't get built because it's missing the `--enable-x11' flag.

A much more minor problem is that it neglects to install the `xscheme.el' file
bundled in the tarball.


* Additional info
I consulted MIT/GNU Scheme maintainer Riastraidh on #scheme@freenode and he said
the makefile in the basedir of the tarball shouldn't be used, and that `src' and
`doc' should be built independently.

I wrote up a patch (see below) that ignores said makefile and manually visits
both directories to run `make'.


* Steps to reproduce:
In above order;

** In shell:
% man mit-scheme
No manual entry for mit-scheme
% info mit-scheme-user
info: No menu item 'mit-scheme-user' in node '(dir)Top'

** In the REPL:
1 ]=> (load-option 'x11)
;Unknown option name: x11

** In Emacs:
M-x load-library xscheme RET
Cannot open load file: No such file or directory, xscheme


* Fix:
