[Buildroot] [PATCH] make busybox build honnor the "none" strip option

[Nicolas Pitre]

The busybox build insists on doing its fancy link and strip dance,
ignoring the externally provided STRIP variable.  It however tries to
avoid stripping when -elf2flt is found in LDFLAGS or CFLAGS, but a
properly configured toolchain won't need to have -elf2flt there, and
there might be legitimate reasons to not strip busybox even on non uClinux
systems.

Fortunately there is a SKIP_STRIP variable that we can set directly.
