Cross compilation fails in GCC

[akku1139]

I'm cross-compiling the Linux kernel using arm-none-eabi-gcc, but sccache throws up some errors and doesn't work.

linux $ export CROSS_COMPILE="sccache /bin/arm-none-eabi-"
linux $ make -j10
  SYNC    include/config/auto.conf
sccache: error: failed to execute compile
sccache: caused by: Compiler not supported: "/bin/arm-none-eabi-ld: cannot open output file a.out: Permission denied\n"
sccache /bin/arm-none-eabi-ld: unknown linker
scripts/Kconfig.include:57: Sorry, this linker is not supported.
make[3]: *** [scripts/kconfig/Makefile:85: syncconfig] Error 1
make[2]: *** [Makefile:730: syncconfig] Error 2

(It seems to start with a vmlinux link because I completed the build without sccache)
