Subject: [PATCH] build: name the sdcc/ revision in the toolchain line

A commit hash can be looked up directly, a checksum cannot. Print the last commit that touched sdcc/, with -dirty for local changes, and fall back to the checksum when git is not available. The toolchain directory keeps the checksum.
