[Linux-ia64] arch/ia64/Makefile tweak

If the gcc in your PATH is version 2.X and you are not 
using cross tools (the CROSS_COMPILE make macro is null) 
`make CC=<path to a 3.X gcc>` fails due to the lack of
--param max-inline-insns=2000 on the compile lines.

This happens because GCC_VERSION in arch/ia64/Makefile is 
determined using $(CROSS_COMPILE)$(HOSTCC) which expands 
"gcc" picking up gcc 2.X.  With GCC_VERSION defined as 2 the 
additional CFLAGS options within the ifneq ($(GCC_VERSION),2) 
are not being added.

You can work around the problem by also setting HOSTCC on the
make command line
  e.g. `make CC=<path to a 3.X gcc> HOSTCC=<path to a 3.X gcc>`
but I believe the correct solution is to use $(CC) instead of
