GDB will have to load two shared libraries (glibc+iconv) instead of just one
(glibc).  This is against the "How To Write Shared Libraries" recommendation.

GDB is also being called from various scripts.  GDB currently does not allow to
make the iconv list initialization lazy due to its existing commands
infrastructure.  Thanks for the advice how to optimize it on the GDB side.
