two variables: TOOLCHAIN_MISSING -- set to "yes" on platforms for which there is no working in-tree toolchain (hppa, ns32k, sh5, x86_64). EXTERNAL_TOOLCHAIN -- if defined by the user, points to the root of an external toolchain (e.g. /usr/local/gnu). This enables the cross-build framework even for TOOLCHAIN_MISSING platforms. If TOOLCHAIN_MISSING is set to "yes", MKGDB, MKBFD, and MKGCC are all unconditionally set to "no", since the bits are not there to build. If EXTERNAL_TOOLCHAIN is set, MKGCC is unconditionally set to "no", since the external toolchain's compiler is not in-sync with the in-tree compiler support components (e.g. libgcc). * Set MACHINE_CPU much earlier in bsd.own.mk, so that more tests in that file can use it.
