#86 made error message for already defined label clearer

build.cpp line 1000:

else ERROR_MSG("Error: label \"%s\" already declared in
section/function\n",name);

this would not clarify if it's a section or function
where the label is already defined in.
the following code would, just replace the whole line.

else ERROR_MSG("Error: label \"%s\" already declared in
%s\n",name,build_cursection_isfunc?"function":"section");

i think it should be implemented as its an easy task
and would make the error msg a bit more clear and
debugging easier.

a bit shorter but works too:

else ERROR_MSG("Error: label \"%s\" already declared in
%s\n",name,build_cursection?"section":"function");

(old one checked if function or not, new one checks if
section or not)

The second version doesn't work because build_cursection is
not NULL for functions as well. I've used the first version,
thanks.
