            Bug ID: 86371
           Summary: building compiler tries to look in $HOME/local/include
           Product: gcc
           Version: 8.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: hsa
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

When building the compiler, the makefile attempts to compile something with "-I
$HOME/local/include".  This is almost certainly a bug (did you want
/usr/local/include ?).  The compiler shouldn't depend on what the
compiler-builder user has in $HOME.  I actually make $HOME unreadable while
building the compiler, so this bug causes the compiler build to fail as it
tries to read a directory to which it does not have permissions.

The bug can be seen with following build commands:
../gcc-8.1.0/configure --enable-language=all
HOME=/THIS_IS_A_BUG_IN_BRIG_XXX make > gcc-make.log 2>&1
grep THIS_IS_A_BUG_IN_BRIG_XXX gcc-make.log
