installer: build with the toolchain from the tree

Browse Source 
The installer Makefile called whatever sdcc was on the PATH, so an
installer built by hand came out of the system compiler, without the
fixes in sdcc/. Use the same toolchain/sdcc-<cksum> as the main Makefile,
built on demand by sdcc/build.sh if a bare installer build gets there
first, and keep CC= on the command line as the way to pick another
compiler. The README example shows the new command lines.
