sel4: update tools to currently used version 9.0.x Until now, Genode referenced a fork of the outdated elfloader-tool to enable bootstrapping of sel4 on ARM platforms. Because the elfloader is inherently dependent on the used platforms newer ARM versions supported by the kernel could not be loaded by the outdated elfloader. This commit uses a fresh fork of the nowadays used sel4_tools repository. Ref #3251

sel4: fix segmentation fault with CCACHE=yes Building the elfloader in kernel-sel4.inc has a problem with Genodes CCACHE make variable. When issuing ... ! ./tool/depot/create mstein/bin/*/base-sel4-* CCACHE=yes ..., building the elfloader used to consume all memory of the host system and then run into a segmentation fault: ! make[6]: *** [elfloader/elfloader.o] Segmentation fault (core dumped) This is because the other build system invokes the CCACHE variable as a command in front of the compiler command. If CCACHE is set to 'yes', the 'yes' command is called and produces an endless output into some output file. The problem can be fixed by locally re-setting the CCACHE variable for the 'make ... elfloader' command to 'ccache' (Genode CCACHE==yes) or '' (Genode CCACHE!=yes). Fixes #4212
