Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh, avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain and depends it means 'build gcc with libssp'. Musl no longer uses libssp (1877bc9d8f), it has internal support, so SSP_SUPPORT was disabled leading some package to not use SSP. No information why Glibc and uClibc use libssp, but they may also provide their own SSP support. uClibc used it own with commit933b588e25but it was reverted inf3cacb9e84without details. Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT if either USE_MUSL or GCC_LIBSSP. Signed-off-by: Julien Dusser <julien.dusser@free.fr>

If your target CPU does not have a Floating Point Unit (FPU) or a
|
|
kernel FPU emulator, but you still wish to support floating point
|

functions, then everything will need to be compiled with soft floating
