Seems to catch more -# problems, such as ' or ` or -- in a link. -# 20051210: Prefer qfile from portage-utils over equery if it's available. -# Check for ... in "link" lines because configure checks are not links. -# Change get_link_generic() to handle whole lines at a time instead of single -# words, so get_linklines() works. -# 20051210: Rework get_libnames() to use a new style of grep, because the old -# way was broken on some packages from the \b. Also optimize the "Looking for -# libraries" section to only grep the log file once for links and cache it; -# also only grep the link lines ones for a given library, then parse the -# output for static or shared. Should speed things up considerably for large -# packages.
