Hi,
when using "-shared -Wl,-G" to create AIX shared libraries for use with runtime
linking,
without also using "-Wl,-brtl" collect2 still does search for lib.a before
lib.so,
eventually registering global constructors found in static lib.a, which are not
exported
by lib.so, so the subsequent link step fails resolving these symbols.
Thank you!

Accept all flags that enable aix runtime linking to change the
library search order. Also there is a disabling flag.
* collect2.c (aixrtl_flag): Enabled by -G and -bsvr4 too. Disabled
by -bnortl. No false positive on -brtllib or -bnortllib.
