dockcross/common.crosstool
Dan Jacques 7dd46fa045 Implement "ct-ng" building, add "linux-mips".
Add a mechanism to construct a full cross-compiler environment using the
"crosstool-ng" cross-compiler building utility. This is implemented in
the new "common.crosstool" include, and augments the "dockcross/base"
base image.

Update Makefile to consolidate Dockerfile generation, notably the
"sed"-based inclusion directives.

Finally, employ all of this to generate a "linux-mips" 32-bit hard-float
MIPS cross-compiler Dockcross image.

# crosstool.common
#
# Common Docker instructions to install "crosstool-ng" and build a full
# cross-compiler suite from a crosstool-ng configuration, CROSSTOOL_CONFIG.
#
# This import complements the "dockcross/base" image, adding:
# - "ct-ng", a cross-compiler building utilty.
# - A cross-compiler suite configured in "crosstool-ng.config".
#
# The generated cross-compiler will have a CROSS_ROOT of:
# ${XCC_PREFIX}/${CROSS_TRIPLE}
#
# A given platform will need to supply the appropriate "crosstool-ng.config" to
# generate its cross-compiler. This can be built using "ct-ng menuconfig" to
# generate a configuration.
# Install Debian packages required for `ct-ng`.
