Subject: Makerules: Do not require startup files for format.lds probe object

During statically linked bootstrap, the compiler does not have
the required startup files, so do a smaller dummy link to obtain
the output format information.

Fixes commit 87d583c6e8cd0e49f64da76636ebeec033298b4d ("install:
Replace scripts/output-format.sed with objdump -f [BZ #26559]").
