Because that's the way how the ELDK is designed.

At least with ELDK, which supports a wide range  pf  processor  fami-
lies,  it  also has to carry information about which CPU architecture
you are targeting for.

ELDK uses two methonds to find out what you  might  want  to  do:  it
checks  the  content of CROSS_COMPILE, and it checks the name you use
to run the tools.

If you set CROSS_COMPILE=powerpc-linux- and run  "ppc_8xx-gcc"  there
is still some indication that, for example, you are on a system which
has  no FPU and only short cache lines. But with above usage, no such
information is available.

All this (including the legal values to be used for CROSS_COMPILE) is
described in the manual; please RTFM for details.

Ignoring the documentation and doing non-standard things is asking for
trouble.

Best regards,

Wolfgang Denk
