Description of problem:
find-provides.perl and find-requires.perl both use:
      tr [:blank:] \\n
Unfortunately, the [:blank:] isn't quoted, so the shell treats it as a filename
globbing pattern.  If you happen to have a file called 'l' in the current
directory when you start a build of a perl package, the dependencies get
completely messed up.

Version-Release number of selected component (if applicable):
4.0.2-8

How reproducible:
Always

Steps to Reproduce:
1. obtain perl-DBD-MySQL source package.
2. create a file called 'l' in the current directory
3. rpm --rebuild perl-DBD-MySQL-1.2216-4.src.rpm
4. Check the build log for errors at the find-provides stage:
   /usr/lib/rpm/perl.prov: Could not open file: '/var/tmp/per' : No such file or
directory
5. rpm -q --requires -p perl-DBD-Mysql-1.2216-4.*.rpm

Actual Results:  Wrong dependency information generated.

Expected Results:  Correct dependency information. 8)

Additional info:

its a pain, because when it happens, the cause is very non-obvious, and isn't
easy to track down.

The fix is simple - just add single quotes around the two [:blank:] in
find-provides.perl and one [:blank:] in find-requires.perl

The perl package also has its own find-provides and find-requires which seems to
suffer the same problem.
