Description:
configure.in decides whether the build could use assembler versions of string functions by doing a test compile. This test compile uses $AS command, which is set as

if test "$ac_cv_prog_gcc" = "yes"
then
  AS="$CC -c"
  AC_SUBST(AS)
else
  AC_PATH_PROG(AS, as, as)
fi

on opensolaris with certain configure settings it succeeds, but the real build fails, because Makefile uses a different command: $CCAS $CCASFLAGS -c

How to repeat:
build on x86-64 opensolaris with

  CFLAGS=-m64 ./configure --enable-assembler && make

Suggested fix:
use "$CCAS $CCASFLAGS -c" in the test compilation in configure.in - the same command line that Makefile uses (compare with the Makefile to get it identical).

remove the code that sets AS from configure.in - AS is not used anyway.

Thank you for the report.
