toolchain-external: convert to the package infrastructure This commit converts the 'toolchain-external' logic to the package infrastructure. The TOOLCHAIN_EXTERNAL_DIR variable (which points to where the toolchain is located) is renamed to TOOLCHAIN_EXTERNAL_INSTALL_DIR, because the former conflicts with the package infrastructure (which defines the <pkg>_DIR variable for each package as pointing to its build directory). The new _EXTRA_DOWNLOADS mechanism is used for Blackfin toolchains. The extract, configuration and installation steps are converted inside the <pkg>_EXTRACT_CMDS, <pkg>_CONFIGURE_CMDS and <pkg>_INSTALL_STAGING_CMDS.

toolchain-external: introduce toolchain-external-package The toolchain-external-package infrastructure is just a copy of the toolchain-external commands, replacing TOOLCHAIN_EXTERNAL by $(2) and adding double-dollars everywhere. toolchain-external itself is converted to a virtual package, but it is faked a little to make sue the toolchains that haven't been converted to toolchain-external-package yet keep on working. The TOOLCHAIN_EXTERNAL_MOVE commands don't have to be redefined for every toolchain-external-package instance, so that is moved out into the common part of pkg-toolchain-external.mk. The musl-compat-headers dependency stays in the toolchain-external package itself. The musl ld link is duplicated in the legacy toolchain-external and the toolchain-external-package, because they have separate hooks. The handling of TOOLCHAIN_EXTERNAL_BIN deserves some special attention, because its value will be different for different toolchain-external-package instances. However, the value only depends on variables that are set by Kconfig (BR2_TOOLCHAIN_EXTERNAL_PREFIX and BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD) so it can easily be used in the generic part. So we don't have to do anything specific for this variable after all.

Fix makefile include order by using sort/wildcard. The 'include' directive in GNU make supports wildcards, but their expansion has no defined sort order (GLOB_NOSORT is passed to glob()). Usually this doesn't matter. However, there is at least one case where it does make a difference: toolchain/*/*.mk includes both the definitions of the external toolchain packages and pkg-toolchain-external.mk, but pkg-toolchain-external.mk must be included first. For predictability, use ordered 'include $(sort $(wildcard ...))' instead of unordered direct 'include */*.mk' everywhere. Fixes [1] reported by Petr Vorel: make: *** No rule to make target 'toolchain-external-custom', needed by '.../build/toolchain-external/.stamp_configured'. Stop.
