Thank you Jon , I just removed "--with-newlib" and it worked and 
generated libgcc.a.
Now I am trapped with uClibc building , uclibc error :

make[1]: `lib/ld-uClibc.so' is up to date.
CC ldso/libdl/libdl.oS
AR cr ldso/libdl/libdl_so.a
STRIP -x -R .note -R .comment ldso/libdl/libdl_so.a
CC libc/sysdeps/linux/arm/brk.os
CC libc/sysdeps/linux/arm/ioperm.os
CC libc/sysdeps/linux/arm/iopl.os
CC libc/sysdeps/linux/arm/mmap.os
CC libc/sysdeps/linux/arm/posix_fadvise.os
CC libc/sysdeps/linux/arm/posix_fadvise64.os
CC libc/sysdeps/linux/arm/sigaction.os
CC libc/sysdeps/linux/arm/__syscall_error.os
CC libc/sysdeps/linux/arm/syscall.os
libc/sysdeps/linux/arm/syscall.c: In function 'syscall':
libc/sysdeps/linux/arm/syscall.c:28: error: '__NR_syscall' undeclared 
(first use in this function)

This type would be more easier,after all we have the right libgcc.a. 
Going closing to success!

Thank you.
