You need to add it to config_host.mk.in to have it visible in 
solenv/gbuild/gbuild.mk (or use the newly introduced mechanism of adding 
a config/config_*.h that you then include in sal/osl/unx/salinit.cxx, 
removing the change from solenv/gbuild/gbuild.mk again).

Did you configure --enable-dbgutil or at least --enable-debug?

Also, the definition of sal_use_syslog in sal/osl/all/log.cxx is in an 
unnamed namespace, so the extern declaration in sal/osl/unx/salinit.cxx 
is unrelated (and the code should result in a link error?); so move the 
definition out of the unnamed namespace.  It would be best to place the 
extern declaration into a header anyway, but it looks like there is no 
good header directory that would be included from both sal/osl/all and 
sal/osl/unx, so short of that please at least add comments to the 
declaration and definition linking those two together across the two 
.cxx files.  And in any case, wrap sal_use_syslog in #ifdef ENABLE_SYSLOG.
