fixed some cross-compiling problems in build files

- specifying $(includedir) to AM_CPPFLAGS caused problems when --prefix was set to /usr during cross-compliation since header files for the cross compiler conflicted with files in $(includedir)=/usr/include. 
- the same applies to $(libdir) in LDFLAGS or something similar
