            Bug ID: 13236
           Summary: Can't compile linux 5.4.8 (with gcc 10 on host)
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org

  Target Milestone: ---

I'm trying to build an image for olimex olinuxino maxi board.

Linux 5.4.8 build fails with this error:

/usr/bin/ld : scripts/dtc/dtc-parser.tab.o:(.bss+0x20) : multiple definitions
of « yylloc »;

It looks very similar to this problem which seems to be solved for dtc package:

I solved it by applying this modification in linux build directory:
https://git.kernel.org/pub/scm/utils/dtc/dtc.git/commit/?id=0e9225eb0dfec51def612b928d2f1836b092bc7e

I don't know if this is a Linux bug or if it is fixed and you just have to pick
a new version.
