[local-time-devel] Fix for SBCL conditional compile

[Attila Lendvai]

> While ASDF was compiling the version of local-time that I installed
> using clbuild, I ran into an error.  It turns out that the compile time
> call to PACKAGE-WITH-SYMBOL? was wrapped in an IF statement, even though
> both results from the call would always evaluate to T, causing a call to
> an SBCL function that doesn't exist in my version (1.0.23) to be included.

pushed (without much testing), thanks!
