Bryan Drewery fcd2678171 Allow specifying an alternative LD_LIBRARY_PATH for the ldd(1) lookup.
This is needed to be able to run check-links.sh against a "sysrooted"
binary while ensuring that the ldd(1) call done on the host uses the
host libc.  It is not possible to set LD_LIBRARY_PATH before calling
check-links.sh as then the "sysrooted" libc would be incorrectly used.

A LD_PRELOAD=libc.so is used to ldd(1) as it needs to use the host libc
to run.  ldd(1) is a simple wrapper around execve(2) and dlopen(2) with
env LD_TRACE_LOADED_OBJECTS set.  Due to the dlopen(2) restriction on
shared library tracing ldd(1) is still required for this lookup.
