Arnd Bergmann 8ab2ae655b default exported asm symbols to zero
With binutils-2.26 and before, a weak missing symbol was kept during the
final link, and a missing CRC for an export would lead to that CRC being
treated as zero implicitly.  With binutils-2.27, the crc symbol gets
dropped, and any module trying to use it will fail to load.

This sets the weak CRC symbol to zero explicitly, making it defined in
vmlinux, which in turn lets us load the modules referring to that CRC.

The comment above the __CRC_SYMBOL macro suggests that this was always
the intention, although it also seems that all symbols defined in C have
a correct CRC these days, and only the exports that are now done in
assembly need this.
