Subject: tools/nolibc: prefer the llseek syscall
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=19c5a681b2262fe30c027aefb3df637f69df140f;p=thirdparty%2Flinux.git

tools/nolibc: prefer the llseek syscall

Make sure to always use the 64-bit safe system call
in preparation for 64-bit off_t on 32 bit architectures.
