16	mmm not quite ... the SYSROOT is for the system packages which implies no
17	tailoring should really be done. TGTROOT is where all customization should
18	be done. if you want to do the customization in the SYSROOT, then it'd be
19	better to have separate sysroots ... so something like:
20	/usr/armeb-booga1_softfloat-linux-gnu/
21	/usr/armeb-booga2_softfloat-linux-gnu/
22	these are tuples that'll work with crossdev:
23	crossdev --target armeb-booga1_softfloat-linux-gnu
