help with --enable-headless build failing in solver

Hi Matus,

i cannot build --enabled-headless on latest master:

/home/rm/src/libo/solenv/gbuild/Package.mk:44: *** gb_Deliver_deliver: 
file does not exist in solver, and cannot be delivered: 
/home/rm/src/libo/solver/unxlngx6.pro/xml/component/desktop/source/splash/spl.component. 
 Stop.

git suggests that spl related stuff was last touched in
90750f0cbc775505e284d085998d326b2abc1471 . But my untrained eyes don't 
see anything wrong there. Do you have any hint?

While digging i find another occurence of spl. Then i found an 
occurrence of Library_spl_unx which AFAIU given this 
scp2/source/ooo/file_library_ooo.scp hunk:

#if defined UNX && !defined MACOSX && !defined LIBO_HEADLESS
STD_LIB_FILE( gid_File_Lib_Spl_Unx, spl_unx)
#endif

does not make sense to build right? So does the patch below looks 
correct? If not care to explain?
