Miika-Petteri Matikainen 26816ed954 Fixes preprocessor regression causing hang
Cppcheck 1.76 introduced a regression in preprocessor which causes
the following code to hang:

    $ cat > test.c << EOF
    #ifndef Y
    #else
    #endif
    EOF
    $ cppcheck -D BAR --force test.c
    Checking test.c ...
    ^C

This used to work with version 1.75. Git bisect reveals that this
regression was caused by commit:
ff036c8742

This commit fixes the regression by avoiding infinite loop in
hasDefine(). If cfg is empty string "", we can skip the whole loop
and exit early.
