[Buildroot] [PATCH 2/2 v2] packages/sox: unconditionaly disable custom SSP detection

[Yann E. MORIN]

From: Yann Droneaud <ydroneaud at opteya.com>

sox implements a custom mechanism to detect whether the toolchain has
SSP suport or not. In doing so, it explicitly tries to see if libssp.so
is present, in which case it unconditionally links with it, even though
the compiler, if left by itself, would have used the SSP support
provided by the C library.

However, with Buildroot, the SSP options arfe handled in our gcc
wrapper, so packages should just not bother with that.

It turns out that, when sox is configured with --disable-stack-protector,
it does not disable it, but really does nothing, which is good for us.

Currently, SSP is conditionally disabled in sox, under various
conditions: that the toolchain does not have SSP, or that it is one of
the know SSP-challenged (i.e. broken) toolchains. Those conditions dates
back tpo before our wrapper started handling that.

Remove all those conditions, unconditionally disable SSP in sox, and let
our gcc wrapper handle the SSP options.
