Subject: lib/Kconfig.debug: fix frv build failure
From: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx>
[ Upstream commit da0510c47519fe0999cffe316e1d370e29f952be ]
The build of frv allmodconfig was failing with the errors like:
/tmp/cc0JSPc3.s: Assembler messages:
/tmp/cc0JSPc3.s:1839: Error: symbol `.LSLT0' is already defined
/tmp/cc0JSPc3.s:1842: Error: symbol `.LASLTP0' is already defined
/tmp/cc0JSPc3.s:1969: Error: symbol `.LELTP0' is already defined
/tmp/cc0JSPc3.s:1970: Error: symbol `.LELT0' is already defined
Commit 866ced950bcd ("kbuild: Support split debug info v4") introduced
splitting the debug info and keeping that in a separate file. Somehow,
the frv-linux gcc did not like that and I am guessing that instead of
splitting it started copying. The first report about this is at:
https://lists.01.org/pipermail/kbuild-all/2015-July/010527.html.
I will try and see if this can work with frv and if still fails I will
open a bug report with gcc. But meanwhile this is the easiest option to
solve build failure of frv.

Generate debug info into separate .dwo files. This significantly
reduces the build directory size for builds with DEBUG_INFO,
