(perl #131786) avoid a duplicate symbol error on _LIB_VERSION
For -flto -mieee-fp builds, the _LIB_VERSION definition in perl.c and
in libieee conflict, causing a build failure.
The test we perform in Configure checks only that such a variable exists
(and is declared), it doesn't check that we can *define* such a variable,
which the code in pp.c tried to do.
So rather than trying to define the variable, just initialize it during
our normal interpreter initialization.
