Timothy Gu dd4d709be7 x86inc: Clear __SECT__
Silences warning(s) like:

    libavcodec/x86/fft.asm:93: warning: section flags ignored on
    section redeclaration

The cause of this warning is that because `struc` and `endstruc`
attempts to revert to the previous section state [1].

The section state is stored in the macro __SECT__, defined by
x86inc.asm to be `.note.GNU-stack ...`, through the `SECTION`
directive [2].

Thus, the `.note.GNU-stack` section is defined twice
(once in x86inc.asm, once during `endstruc`), causing the warning.

That is the first part of the commit: using the primitive `[section]` format
for .note.GNU-stack etc., which does not update `__SECT__` [2].

That fixes only half of the problem. Even without any `SECTION` directives,
`__SECT__` is predefined as `.text`, which conflicting with the later
`SECTION_TEXT` (which expands to `.text align=16`).
