This fixes a warning from Apple's clang compiler:

/Users/travis/build/stweil/tesseract/src/ccutil/errcode.cpp:83:7: warning: indirection of non-volatile null pointer will be deleted, not trap [-Wnull-dereference]

Even with installed asciidoc and xsltproc the build will fail if
xsltproc cannot find the required stylesheet
http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl.
Ignore such errors until there is a better check in configure.

at program start should be faster than computing them on demand.

It's a false positive, but setting the variable to 0 satisfies the compiler.
