kbuild: use INSTALLKERNEL to select customized installkernel script
Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

70Install script called when using "make install".
71The default name is "installkernel".

73The script will be called with the following arguments:
74 $1 - kernel version
75 $2 - kernel image file
76 $3 - kernel map file
77 $4 - default install path (use root directory if blank)

79The implmentation of "make install" is architecture specific
80and it may differ from the above.

82INSTALLKERNEL is provided to enable the possibility to
