Bug ID: 102755
Summary: Built gcc cross compiler always tries to use "as"
instead of cross assembler
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

Proposed minimal fix
In gcc.c the assembler name is hard coded as "as" and the --with-as option does
not change this. When building an aarch64-linxu-gnu cross compiler the build
process used aarc64-linux-gnu-as but the built cross compiler attempted to use
"as", which does not work. While I could override the spec file that is a
suboptimal solution.
This affects at least the gcc-12 tip version and probably most other versions
too. The proposed fix has been tested without --with-as and with
--with-as=/usr/local/bin/aarch64-linux-gnu-as.
