libtool: Prefer response files over linker scripts for mingw tools
The GCC/binutils tools support response files just fine, while
lld (impersonating GNU ld) only supports response files, not
linker scripts. Using a linker script as input just to pass a
list of files is overkill for cases when a response file is enough.
* build-aux/ltmain.in: Move creation of ld script.
* m4/libtool.m4: Add new variable tag for file_list_spec.
