Subject: tools/nolibc: open files with O_LARGEFILE
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ce7677458e680d0742fb7f86c0e27272e4c56205;p=thirdparty%2Fkernel%2Flinux.git

tools/nolibc: open files with O_LARGEFILE

nolibc can natively handle large files. Tell this to the kernel by
always using O_LARGEFILE when opening files. This is also how other
libcs do it.
