x86 asm: mark stack as non-executable
...
Gentoo's `scanelf` QA tool detects writable/executable stack
of assembly-writtent files as:
```
$ scanelf -qRa .
0644 LE !WX --- --- ./src/strategies/x86_asm/.libs/picture-x86-asm-sad.o
0644 LE !WX --- --- ./src/strategies/x86_asm/.libs/picture-x86-asm-satd.o
0644 LE !WX --- --- ./src/strategies/x86_asm/picture-x86-asm-sad.o
0644 LE !WX --- --- ./src/strategies/x86_asm/picture-x86-asm-satd.o
```
Normally C compiler emits non-executable stack marking (or GNU assembler
via `-Wa,--noexecstack`).
The change adds non-executable stack marking for yasm-based assmbly files.
https://wiki.gentoo.org/wiki/Hardened/GNU_stack_quickstart has more details.
