This selects the native threads implementation for the selected

system and C library.

For example, on Linux with glibc, this is NPTL; on Windows with
|
|
mingw, this is win32.

Extra directories to include in /etc/ld.so.conf. The directories
|
|
will be augmented per compiler's multilib specification,
|
|
if applicable. For example, if the compiler's multilibs include
|
|
/lib and /lib64, and you specify /usr/local/lib here, ld.so.conf
|
|
will have both /usr/local/lib and /usr/local/lib64.

Say 'Y' here if you want to have a ldd-like helper that
|
|
you can run on your build system, and that will (try to)
|
|
resolve shared libraries dependencies as if run on the
|
|
target.
|
|
|
|
Note that the cross-ldd helper is not a full replacement
|
|
for the native ldd. Please see the help, by running it
|
|
with '--help' for more explanations.
