Greetings,

When a shared library that resides in a deeply nested folder contains 
unresolved (long-named, mangled) symbols, the displayed name of the 
library and/or symbol might get truncated.  The attached patch makes the 
size of errbuf (ldso/dynlink.c) configurable (--with-ld-errbuf-size), 
while yet leaving the default size of 128 unaffected.

Best regards,
Zvi
