As I don't have the ownership on the project, I need to patch (and
provide a patch upstream). But this can be tedious on big projects, so
it would great if libtool don't filter the options like -fno-lto,
-fno-whopr.
The path of least resistance is to use the GCC -Wl, or -Wc, syntax to
pass options to the linker or compiler, respectively. This already
works well with Autoconf, Automake, and libtool.
Adding support to libtool to support particular GCC options is the
path of greatest resistance.
Compiler and linker options tend to expand continually, and it is not
reasonable to support them all.
