 Looking at the configure script, I think there's a typo in the section
 that tests for sparc v8+:
 
 [...]
   case "$host_cpu" in
     sparc*)
       if test -n "$GCC"; then
         { printf "%s\n" "$as_me:${as_lineno-$LINENO}: checking whether SPARC v8+
  instructions are supported" >&5
 printf %s "checking whether SPARC v8+ instructions are supported... " >&6; }
 if test ${gl_cv_sparc_v8plus+y}
 then :
   printf %s "(cached) " >&6
 else $as_nop
   cat confdefs.h - <<_ACEOF >conftest.$ac_ext
 /* end confdefs.h.  */
 
 int
 main (void)
 {
 asm volatile ("membar 2");
   ;
   return 0;
 }
 _ACEOF
 if ac_fn_c_try_compile "$LINENO"
 then :
   gl_cv_sparc_v8plus=yes
 else $as_nop
   gl_cv_sparc_v8plus=no
 fi
 rm -f core conftest.err conftest.$ac_objext conftest.beam conftest.$ac_ext
 
 fi
 { printf "%s\n" "$as_me:${as_lineno-$LINENO}: result: $gl_cv_sparc_v8plus" >&5
 printf "%s\n" "$gl_cv_sparc_v8plus" >&6; }
         if test $gl_cv_sparc_v8plus = no; then
 >>>                                 ^          <<<
                               CC="$CC -mcpu=v9"
           CXX="$CXX -mcpu=v9"
         fi
       fi
       ;;
   esac
 [...]
 
 I believe the line marked with ">>> ^  <<<" below it should be "!="
 rather than "=".
