configs: remove uClibc config options

Following the switch to Glibc as the default libc in Buildroot [1],
all defconfigs expecting uClibc with wchar (or any other uClibc
specific option) should now select BR2_TOOLCHAIN_BUILDROOT_UCLIBC too.

Even if all defconfigs has been tested with uClibc, maintainers
prefer to not enforce a C library and use the default of Buildroot,
which is now glibc.

This commit remove uClibc specific options BR2_TOOLCHAIN_BUILDROOT_WCHAR,
BR2_PTHREAD_DEBUG (required by gdb) and BR2_TOOLCHAIN_BUILDROOT_USE_SSP.

Since glibc always has argp built-in, also remove the standalone one
from affected toolchains...
