[Buildroot] [PATCH v4, 1/1] package/libopenssl: set no-asm with generic architectures

[Fabrice Fontaine]

Use no-asm when building statically with a generic architecture such as
gcc or linux-generic32, see
https://github.com/openssl/openssl/issues/9839

This will fix a static build failure on x86_64 due to the removal of
x86/x86_64 BSAES and AES_ASM support by
https://github.com/openssl/openssl/commit/87bea6550ae0dda7c40937cff2e86cc2b0b09491

Fixes:

Changes v3 -> v4 (after review of Thomas Petazzoni):
 - Fix copy/paste error and remove the second assignation

Changes v2 -> v3 (after review of Thomas Petazzoni):
 - Set no-asm with linux-generic32

Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Set no-asm with all static builds and not only x86_64

This doesn't match what you are doing in the code. In the commit log
you say that you're passing no-asm when building statically with gcc or
linux-generic32.

In the code, you are *always* passing no-asm with linux-generic32, even
for non-static builds. Is this intended ?
