X-Git-Tag: upstream/2.34~1067
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0400f928335a5e04c788e1c831d8825d42612c49;p=platform%2Fupstream%2Fglibc.git

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]").
