The ASCII DEL (127) character was appended to the end of every title bar.
This patch fixes the issue by properly assigning PRE_RELEASE_SUFFIX
to an empty string rather than a literal "". The literal double-quotes
were getting defined to the preprocessor as -DPRE_RELEASE_SUFFIX=""""
and after preprocessing, browser.xul had ASCII DEL (127) characters
instead of the empty string.
