Add mksh from CVS 2010/08/24 as system/core/mksh module
Both shells (ash from system/core/sh, and mksh) are built by
default but only the one where $(TARGET_SHELL) is set to is
actually installed (the shell and the mkshrc configuration
file are tagged shell_mksh for this to work).

Don't alias 'stop' to 'kill -STOP'
Android has already has a stop command used
to stop the main runtime and the alias
interferes with testing tools that expect
stop to kill the runtime.

+# The definitions below were generated by examining the
+# output of the following command:
+# make showcommands out/target/product/generic/system/bin/mksh 2>&1 | tee log
+#
+# They are only used to let Build.sh find the compiler, header
+# files, linker and libraries to generate Makefrag.inc (similar
+# to what GNU autotools’ configure scripts do), and never used
+# during the real build process. We need this to port mksh to
+# the Android platform and it is crucial these are as close as
+# possible to the values used later. (You also must example the
+# results gathered from Makefrag.inc to see they are the same
+# across all Android platforms, or add appropriate ifdefs.)
+# Since we no longer use the NDK, the AOSP has to have been
+# built before using this script (targetting generic/emulator).
