Alexander Kabaev 60743cbd22 Do not require pos parameter to be zero in MAP_ANONYMOUS mmap requests
in Linux emulation layer. Linux seems to only require that pos is
page-aligned, but otherwise ignores it. Default FreeBSD mmap parameter
checking is too strict to allow some Linux binaries to run. tsMuxeR is
one example of such a binary.
