Unclearly told...  The right words would have been: "can TRY TO use it 
to compile all kind of things
like a Linux kernel and here the 'libgcc' library".   It has taken years 
since I last compiled a Linux
kernel but I assume it not requiring a 'libgcc' for the target system.  
Producing 'libgcc' however needs
the standard C headers for the target Linux system....   The 
'include/asm*' and 'include/linux', the
"kernel headers", should be enough when producing a Linux kernel, it is 
assumed (by me) to not
require anything from 'libgcc' like "soft-float" routines for a CPU 
without a FPU...
