[PATCH resend] Wrong CRC with ASCII CRC for large files

[Dominique Martinet]

From: Stefano Babic <sbabic@denx.de>

Due to signedness, the checksum is not computed when filesize is bigger
a 2GB.

This patch was originally sent to bugs-cpio in 2017 but seems to have
gotten lost:
https://lists.gnu.org/archive/html/bug-cpio/2017-07/msg00004.html

It has since been handpicked and made its way into yocto[1] and
debian[2], seemingly without issue so I'm giving sending this again
another try (I did not see any other attempt to send this again since
2017).
