When ./configure was run with --disable-smbbranch, the final linking fails 
because of object files refering to symbols XF_SMBget_cache_file and 
XF_SMBget_netfile_cache_dir. 
 
There are macros with the same names defined in smb/smb_module.h.  
The definition of these macros is protected inside a #ifdef USE_SMB_BRANCH, 
but their use in libs/menu.c, libs/callbacks.c, libs/run.c and 
libs/menu_callbacks.c are not protected by a #ifdef, so that the compiler 
assumes them to be functions... 

Reproducible: Always
Steps to Reproduce:
1. ./configure --disable-smbbranch 
2. make  
3.  
 
Actual Results:  
(when linking xffm) 
 
Undefined                       first referenced 
 symbol                             in file 
XF_SMBget_cache_file                ../libs/.libs/libxffm_basic.so 
XF_SMBget_netfile_cache_dir         ../libs/.libs/libxffm_calls.so 
ld: fatal: Symbol referencing errors. No output written to .libs/xffm 
 

Expected Results:  
succesful linking...
