Bug #: 53575
Summary: --with-abi=x32 without --with-multilib-list doesn't
work
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org

if i configure gcc using --with-abi=mx32, but don't specify
--with-multilib-list, then the config will default to
--with-multilib-list=m32,m64. then trying to build gcc will fail as
it will use "." for its os multilib dir instead of "../libx32". if i
specify --with-multilib-list=mx32, then everything works great.
should the config.gcc logic for with_multilib_list==default consult
the with_abi setting ? maybe something like:
if test "$x86_multilibs" = "default"; then
if test "$with_abi" != ""; then
x86_multilibs="$with_abi"
else
x86_multilibs="m64,m32"

I think --with-abi=mx32 should also add x32 run-time
library, in addition to 64-bit and 32-bit ones.
