Don't eval $LDSHFLAGS in configure.in

[Albert Chin]

>From configure.in:
   # The $SHLD and $LDSHFLAGS variables may contain references to other
   # variables so they need to be eval'ed.

However, only Solaris has variables in LDSHFLAGS:
  LDSHFLAGS="-G \${CFLAGS}"

This is redundant though as SHLD="\${CC} \${CFLAGS}" is the default.

Based on these observations, I've attached a patch to remove the eval
of $LDSHFLAGS and treat it as a normal variable.
