Linux fixes [PATCH]

[Jeff Johnston]

Patch checked in, thanks.  Regarding dl-load.c: I am able to build this 
on my FC-4 system.  dl-load.c includes ldsodefs.h which then includes 
dlfcn.h which is found in libc/sys/linux/include and defines 
__RTLD_DLOPEN.  Why aren't you picking this up in your build?
