removed the "bs" build scripts

autotools are somewhat ugly, but that doesn't justify duplicating its
effort with another complex build system.

-bs - build system
------------------
-
-bs is an attempt at a fast and reliable build system that will let
-developers build mpd without having to deal with the complexity of
-autotools.  It is still a work in progress, but it seems to be
-reasonably usable (to developers) and fast.
-
-It is designed from the ground up to work with cross-compilation, as well as
-multiple build targets/configurations from the same source tree (using the O
-variable).
-
-It is NOT intended to replace autotools for distribution maintainers
-or end users who are satisfied with autotools.
-
-SYNOPSIS
---------
-
-# To build mpd in a directory "output"
-./build.mk O=output defconfig
-$EDITOR output/config.mk
-./build.mk O=output
-
-
-FEATURES
---------
-
-* Designed for cross-compilation from the ground up
-* Designed to easily handle multiple build directories from the same source
-  tree.  Just set the O variable when invoking make (see synopsis).
-* Automatic dependency analysis (if using GCC)
-* Highly configurable (no auto-detection of dependencies to get wrong)
-* Simple, no archaic M4 macros or unreadable auto-generated shell or makefiles
-  just human-maintained GNU Make and POSIX shell.
-
-
-config.mk
----------
-
-This is the configuration file a user should edit if they wish to
-enable/disable features or tune settings.  Once created, this
-will NOT be modified by the build system, so user settings will
-always be preserved.
-
-
-VARIABLES
----------
-
-These are conventions, not hard and fast rules (as there's no good way to
-enforce them :)
-mixed-case or lower-case variables are used by bs internally.
-ALL_CAPS variables are designed to be changed by users.
-
-
-REQUIREMENTS
-------------
-
-GNU Make, POSIX shell + common UNIX tools (awk, sed, mv, rm, mkdir).
-git (version control system) is only required if you wish to autodownload
-external dependencies (flac, tremor, mad, etc...) for static linking.
-
-
-BUGS
-----
-
-Modifications to config.mk will over-rebuild.
-
-Changes to CFLAGS/LDFLAGS from the command-line are not yet checked in
-rebuilds.
