+Subject: [PATCH] [m4/libtool.m4] linker error for powerpc64le-unknown-linux-gnu
+
+Hi all,
+
+ 1) As we might know, Gentoo has powerpc64le-unknown-linux-gnu compiler
+
+leno@localhost ~ $ powerpc64le-unknown-linux-gnu-gcc -v
+
+Using built-in specs.

+
+gcc version 5.3.0 (Gentoo 5.3.0 p1.0, pie-0.6.5)
+
+  2) And the supported emulations
+
+leno@localhost ~ $ powerpc64le-unknown-linux-gnu-ld -V
+GNU ld (Gentoo 2.25.1 p1.1) 2.25.1
+  Supported emulations:
+   elf64lppc
+   elf32lppc
+   elf32lppclinux
+   elf32lppcsim
+
+   3) But when I set CHOST="powerpc64le-unkown-linux-gnu" in Gentoo and
+execute aclocal, automake, libtoolize --copy --force, autoconf. When I
+glance in the latest m4/libtool.m4 :
+
+if AC_TRY_EVAL(ac_compile); then
+   case `/usr/bin/file conftest.o` in
+     *32-bit*)
+       case $host in
+...
+         powerpc64le-*linux*)
+           LD="${LD-ld} -m elf32lppclinux"
+           ;;
+         powerpc64-*linux*)
+           LD="${LD-ld} -m elf32ppclinux"
+           ;;
+...
+     *64-bit*)
+       case $host in
+...
+         powerpcle-*linux*)
+           LD="${LD-ld} -m elf64lppc"
+           ;;
+         powerpc-*linux*)
+           LD="${LD-ld} -m elf64ppc"
+           ;;
+...
+
+seems linked to $LD='$LD-ld -m elf64ppc' and failed to compile packages.
+
+ 4)  Below is my workaround patch and works fine for this case.  If this is
+OK for you, Could this to be merged in upstream? Thanks
