[Bug 1270293] [NEW] 32-bit eu-strip fails for files greater than 2 GB.

[Lei Zhang]

Public bug reported:

We have a large binary on a 32-bit host where the following command
failed:

eu-strip -o foo.stripped -f foo.debug foo

eu-strip: while computing checksum for debug information: Invalid
argument

Here, foo.debug is over 2 GB. The crc code called pread() with a
negative offset because crc32_file.c does not have LFS, off_t is only
32-bit, and the offset variable overflowed.

A small patch has already been committed upstream. [1] Any chance we can
backport this to 12.04 LTS?
