--------------------------------+-------------------------------------------
 In build/tools/v2/tools/gcc.jam we are setting the LD_LIBRARY_PATH for
 compilation to:

 /usr/bin:/usr/lib:/usr/lib32:/usr/lib64

 Couple of points:

 - /usr/bin (?) :D
 - /usr/lib on FreeBSD does not contain major number libs so most if not
 all binaries will not pick up anything from here
 - /usr/lib32 on FreeBSD DOES CONTAIN major number libs so if you are
 building on 32-bit this will work, HOWEVER if you are building 64-bit then
 this will cause failures
 - /usr/lib64 does not exist on FreeBSD (I believe this is a Linux thing)

 Based on the comments within gcc.jam I FEEL as do some other people (see
 thread reference) that if bjam is *really* going to rely on rtld then it
 should do so by NOT setting anything to LD_LIBRARY_PATH which many have
 pointed out is only to be used when the standard search path is not
 enough.  Setting this PATH is very dangerous and for 99% of the build
 cases, rtld does the right thing.

 Thread:

 td20143328.html

 If it is decided to set LD_LIBRARY_PATH then we need to make this OS
 specific and unset it for FreeBSD (or minimally add back /lib which Steven
 pointed out in the above thread is probably not the right solution given
 LD_LIBRARY_PATH's semantics).
