Subject: lib/Kconfig.debug: fix frv build failure

From: Sudip Mukherjee <[email protected]>

[ 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.
