Summary

0000387: missing _dl_progname symbol when using libdl from static executables

Description

Patch 11124-11126 (Removed hardcoded ld-uClibc.so.0 in uClibc) in svn tree breaks libdl usage from static executable, since symbol _dl_progname is now defined in ldso.c, which is not available from static executables.

Additional Information

A "fake" (empty) _dl_progname symbol must be defined in libdl.c when compiling static libdl (i.e. when __LIBDL_SHARED__ macro is not defined), together with _dl_library_path, _dl_ldsopath, _dl_errno, etc...). That is, add:
const char *_dl_progname = ""; /* Program name */
just before
char *_dl_library_path = 0; /* Where we look for libraries */
