Changeset 15256 for trunk/source/lisp-kernel/linuxarm/Makefile

Timestamp:

Message:

Be explicit about the fact that CCL doesn't yet support the hard
float ABI.

(The lisp mostly runs if the kernel is built with 'make FLOAT_ABI=hard';
as one would expect, math library calls that take FP args/return FP
values don't behave correctly.)
