[ Upstream commit 38aa192a05f22f9778f9420e630f0322525ef12e ]
The ecc.c file started out as part of the ECDH algorithm but got moved out into a standalone module later. It does not build without CRYPTO_DEFAULT_RNG, so now that other modules are using it as well we can run into this link error:
aarch64-linux-ld: ecc.c:(.text+0xfc8): undefined reference to `crypto_default_rng' aarch64-linux-ld: ecc.c:(.text+0xff4): undefined reference to `crypto_put_default_rng'
Move the 'select CRYPTO_DEFAULT_RNG' statement into the correct symbol.
