[Mingw-w64-public] Simplifying new def addition

[Alon Bar-L. <alo...@gm...>]

Hello,

Just an idea... I had to add pdh.def into current build.

Steps:
1. Add pdh.def into mingw-w64-crt/lib32
2. Add the following to mingw-w64-crt/Makefile.am
    cat << __EOF__ >> mingw-w64-crt/Makefile.am
if LIB32
lib32_SCRIPTS += lib32/libpdh.a
endif
__EOF__
3. Do autoreconf

It would be great if this process was much simpler... Add pdh.def into
mingw-w64-crt/lib32 and that's it.
Of course this applies for "simple" defs.

It can be done easily using autoconf... It can do something like:

autoconf:
---
LIB32_LIBS="$(echo $((cd mingw-w64-crt && find lib32 -name '*.def' ) |
sed 's#\([^/]*\)\.def#lib\1.a#'))"
AC_SUBST([LIB32_LIBS])
---
automake:
---
lib32_SCRIPTS = @LIB32_LIBS@
---

What do you think?
Alon.
