The perl build's attempt to escape spaces and such in LD_LIBRARY_PATH is _SAD_.
It uses a sed expression that assumes you can escape - to use it as a literal (you can't, it has to be first or last char of the range), and assumes you have to escape delimiters in sed [] context (you don't), and/or that non-printf escapes become the literal character (they don't, the backslash is preserved as a literal), meaning it winds up doing "s/[\-\]//" which is a length 1 range, which is officially undefined behavior according to posix, and regcomp errors out. But if we don't accept it (like other implementations do) the perl build breaks. So collapse [A-A] into just [A]. Testcae taken from perl 5.22.0 file Makefile.SH line 8. (While we're at it, remove an unused argument from a function.)
