[Bug c/31133] New: allow to set sysroot via environment variable

[pclouds at gmail dot com]

I use gcc to cross compile a system with --sysroot option. However replace
every gcc command with 'gcc --sysroot=blah' is kind of redundant. It would be
great if I can set environment variable SYSROOT=blah (or GNUSYSROOT=blah) and
leave gcc commands intact, just like CFLAGS and friends.
