Bug ID: 88321
Summary: Crosscompiled gcc does not use precompiled as
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: bugzi...@poradnik-webmastera.com
Target Milestone: ---
I have build gcc 8.2.0 as as crosscompiler for Centos 7 x86_64 -> MinGW x86_64.
Before starting I installed gcc 4.9.3 MinGW crosscompiler from EPEL repository.
My new crosscompiler was configured in following way:

Build also completed successfully. However when I tried to use it, it turned
out that it is broken. Looks that configure script found preinstalled binutils,
but path to it is not hardcoded in built crosscompiler. Here is output from
build with --verbose option:
