fix compilation with LC_ONLY_DECODER

[neheb]

881b5e2 broke compilation by always
defining DRN and DRM_PS. Fix this and place the define where it belongs.

But now you unconditionally enable DRM support, even in the non-DRM build. This cannot be correct, either.

How about this: We pass a new macro at build stage

libfaad_drm_la_CFLAGS = ${libfaad_la_CFLAGS} -DDRM_SUPPORT

and then define DRM and DRM_PS in the libfaad/common.h header file only if this macro is defined

#ifdef DRM_SUPPORT
#define DRM
#define DRM_PS
#endif

so we can #undef them later if LC_ONLY_DECODER is defined.

That's already the case. See: #15

No, it's not. It creates two shared libraries, one with DRM support (libfaad_drm.la) and one without (libfaad.la).
