>Description:
gcc/config.gcc (line 3195) always tries to build multilibs while making cross-compiler for sparc-sun-solaris2.8:

	case $machine in
	*-*-solaris2.[789])
		tm_file="sparc/biarch64.h ${tm_file} sparc/sol2-bi.h"
		if test x$gnu_ld = xyes; then
			tm_file="${tm_file} sparc/sol2-gld-bi.h"
		fi
		if test x$gas = xyes; then
			tm_file="${tm_file} sparc/sol2-gas-bi.h"
		fi
		tmake_file="$tmake_file sparc/t-sol2-64"
		;;
	esac

but while making it, it tries to link the target libs against object files $target/lib directory, not in $target/lib/64/ or $target/lib/sparcv9. Build fails with ld error.
>How-To-Repeat:
<build binutils with --target=sparc-sun-solaris2.8, install them, and install native Sparc headers/libs into $prefix/$target/include and $prefix/$target/libs>

./configure --target=sparc-sun-solaris2.8
make
it'll fail during libiberty linking
>Fix:
$prefix/$target/include
