I posted a series that changed how the "target:" prefix got into the
filenames:

  https://sourceware.org/ml/gdb-patches/2015-07/msg00828.html

Basically this returned the default sysroot to "" and added some logic
in solib_find_1 that would use a prefix of "target:" if no sysroot was
set and no file had been specified--GDB would only retrieve files if
you did "target remote ..." on it's own, a case that didn't really do
much previously.

It was configurable with a new boolean, "set/show auto-target-prefix"
(defaulted to enabled), and if users wanted to specify a file but have
GDB fetch the libraries over RSP that could be done with an explicit
"set sysroot target:".

I quite liked it, but nobody else did! :-)

Cheers,
Gary
