[Bug bootstrap/41529] [4.5 Regression] LTO configuration should detect if the target is ELF

I agree with Andrew, but as a middle way you could put something like this in
config/elf.m4:

dnl usage: ACX_ELF_TARGET_IFELSE([if-elf], [if-not-elf])
AC_DEFUN([ACX_ELF_TARGET_IFELSE]), [
AC_REQUIRE([AC_CANONICAL_TARGET])

target_elf=no
case $target in
  ...) target_elf=yes;;
esac

AS_IF([test $target_elf = yes], [$1], [$2])
])

and use the macro in the toplevel.
