Buildroot always enable largefile support in the toolchain, and thus
the associated definitions are always on. This leads to a problem in
unzip that on a 32-bit arch with these flags being passed in
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
but the LARGE_FILE_SUPPORT define not being set will cause a size
mismatch on the comparison of the zipfiles:
$ unzip test.zip
Archive: test.zip
error: invalid zip file with overlapped components (possible zip bomb)
The simple solution is just enable LARGE_FILE_SUPPORT to enable large
file support. In order to avoid redefinition warnings, we undefine
_LARGEFILE_SOURCE and _LARGEFILE64_SOURCE.
