            Bug ID: 67725
           Summary: all gcc versions has hardcoded LD path with bootstrap
                    on illumos platform
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ikozhukhov at gmail dot com
  Target Milestone: ---

on autotools i can see we try to use for solaris2* targets :
ld=/usr/ccs/bin/ld
example from gcc-4.8.5/gcc/acinclude.m4:
line 518: gcc_cv_sun_ld_ver=`/usr/ccs/bin/ld -V 2>&1`

it is mistake to use hadrcoded ld path because on illumos we have
ld=/usr/bin/ld and we can specify correct path by:
--without-gnu-ld --with-ld=/usr/bin/ld

but by autotools we will try to identify LD version by hardcoded
/usr/ccs/bin/ld and it is mistake.
have to fix it on all gcc versions, because for DilOS (http://www.dilos.org,
illumos based platform) i have plans remove old /usr/ccs links and it will
failed with gcc bootstrap.
