[PATCH 1/2] rust: fix export of bss symbols

[Andreas Hindborg]

From: Andreas Hindborg <a.hindborg@xxxxxxxxxxx>

Symbols in the bss segment are not currently exported. This is a problem
for rust modules that link against statics, that are resident in the kernel
image. This patch enables export of symbols in the bss segment.

Fixes: 2f7ab1267dc9 ("Kbuild: add Rust support")
