as this is already provided by value.h, and was actually causing
a compilation error because of a conflict in parameter type
declaration due to a missing const keyword.

updated related comments. Do not set the minimal symbol table to
mst_solib_trampoline for ST_ENTRY symbols with SS_LOCAL scope
in a dynamic executable.

where we are unable to find the minimal symbol for the given
