kern-tools: fix merge_config when LD contains parameters
To ensure that the kernel linker is used when allno/mod/yes config
merge_config steps were executed, the call to make was tweaked to
explicitly pass LD.
But since the variable wasn't quoted, any parameters to LD (like
the sysroot) were mistakenly passed to make, and hence could trigger
an error on some architectures.
We also tweak the logging to hightlight errors like this in the
future and avoid losing it in the noise of merge configs sometimes
overly verbose output.
