I come to this via build instruction from branch 4.4 at https://github.com/openatv/enigma2 

I build: MACHINE=vuduo2 DISTRO=openatv DISTRO_TYPE=release make image

It is kind of strange that building image I end up now on this error instead of bug https://bugzilla.yoctoproject.org/show_bug.cgi?id=14169

Other guy with this issue (including full log):

Solution:
change in pseudo_ipc.h the enum definition:

enum pseudo_access_t_enum {
	PSA_EXEC = 1,
	PSA_WRITE = (PSA_EXEC << 1),
	PSA_READ = (PSA_WRITE << 1),
	PSA_APPEND = (PSA_READ << 1)
};

typedef enum pseudo_access_t_enum pseudo_access_t_enum;
extern pseudo_access_t_enum pseudo_access_t;


then add into pseudo_ipc.c the line:

pseudo_access_t_enum pseudo_access_t;


With this, variable exists only once for this tool.
