Marco Casaroli 5513029711 arch/arm: Build a loadable module and a shared library as FDPIC too. 
CONFIG_FDPIC teaches the ELF module path what an FDPIC object is, so an
application built as a module gets -mfdpic -fPIC and the
arm-uclinuxfdpiceabi linker.  The loadable module path, which apps builds
with DYNLIB = y and which apps/Library.mk uses for a shared library, was
left as it was: a -r partial link with the stock linker.  That leaves an
object with no dynamic section, so the loader has nothing to bind an import
to, and there is no way to build a library an FDPIC module can call.

Give that path the same treatment.  CMODULEFLAGS and CXXMODULEFLAGS gain the
FDPIC compiler flags, and LDMODULEFLAGS links a shared object rather than a
partial one.  The entry point is left to the caller, because a module is
entered at _start while a library is only ever called into.

CXXMODULEFLAGS is also defined for the first time.  apps/Library.mk compiles
every C++ source of a shared library with it and no architecture defined it,
so those sources were compiled with no architecture flags at all.
