Hello, I have a problem building cross toolchain for i486 based system. 
I set x86 i486 architecture to the target options and add 
--with-cpu=i486 to glibc options in menuconfig. However according to 
glibc config.log only main configure script is called with 
--with-cpu=i486 parameter, other configure scripts are called with i686 
arch. config.log is attached. This results in SIGILL in threaded 
application since libpthread is using unsupported cpuid.
