Comment (by leif):
Replying to [ticket:14296 jdemeyer]:
> Unfortunately, there can be an inconsistency between `$LD` and the
linker used by GCC, leading to build failures.
This affects only a few spkgs. IMHO we should fix these, by changing
their `spkg-install` scripts, or -- much better -- patching the upstream
sources and reporting the fixes upstream.
> We should do the following:
> 1. If `$LD` is unset, set it to `$CC -print-file-name=ld` by default
instead of `ld`.
Agreed.
> 2. If `$LD` is set and the value differs from `$CC -print-file-name=ld`,
force building of the GCC spkg (define these values to be equal if the
output of `command -v VALUE` is equal).
That's a bit overkill. Ok for a buildbot, but otherwise we should just
issue a warning (or, more complicated, error out unless some override
setting is active).
