Greetings folks
In regards to previous conversations on this list and a desire to post
something that is not considered "idle speculation"
find attached a build recipe for creating a multilib cross-toolchain
that neither misuses -B/foo/lib nor uses the untolerably
heinous and evil STARTFILE_PREFIX_SPEC.
This is only part 1, the initial cross-toolchain
Find attached compiler test output for both 32bit and 64bit
Note that nothing strays outside of the sandbox (not includes, not
library search paths)
Also note the search paths in the linker scripts (especially the 64bit
build)
-m32 and -m64 switches dont require any help from misusing -B/foo/lib to
find the startfiles and the library searches are sane
Now have to move the whole lot over to a 64 bit machine to test the rest
Best Regards
