Bug ID: 67590
Summary: libcc1 cannot find objdump when cross build native
Product: gcc
Version: 5.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: syq at debian dot org
Target Milestone: ---
The configure of libcc1 uses gcc_cv_objdump var when cross build native.
while it is not defined at all.
So we can use gcc/configure.ac one.
