Released SDCC 4.5.0 and 4.6.0 miscompile some of our code in the mcs51 register allocator (SDCC bugs 4153 and 4154, fixed in trunk r17025 and r17039). The first make now downloads the 4.6.0 sources, checks their sha256, applies the two fixes from sdcc/ and installs the compiler into toolchain/, named after a checksum of sdcc/, so a changed patch builds a new one. make CC=sdcc still uses an installed compiler.
