[PATCH 5.6.1] OPTIMIZE=-g

make OPTIMIZE=-g is not enough on OS/2 to debug an extension, since
some optimization flags are put on the linker line too.

This patch puts $(OPTIMIZE) on the DLL link line - but to minimize
problems, this is done on OS/2 only.  Simultaneously "strip" flag '-s`
is removed from LDDLFLAGS (since it is already present on OPTIMIZE).

Enjoy,
Ilya
