[Buildroot] [PATCH 1/1] package/libopenssl: fix static build on x86_64

[Fabrice Fontaine]

Use no-asm when building statically on x86_64, see
https://github.com/openssl/openssl/issues/9839

Fixes:

Is the problem specific to x86-64 ? Reading the Github issue, the
OpenSSL developer apparently says that whenever the "generic"
architecture variants are used, no-asm should be passed as well. This
is not really what your patch is doing.

Could you clarify this ?
