YAMAMOTO Takashi ff3fa805a4 libxx: Use Kconfig "choice" to specify an implemenetation
It doesn't make sense to enable both of LIBCXX and UCLIBCXX.
This commit reflects it to Kconfig.

config C99_BOOL8
bool "sizeof(_Bool) is 8-bits"
default n
---help---
This setting means (1) your C++ compiler has sizeof(_Bool) == 8, (2)
your C compiler supports the C99 _Bool intrinsic type, and (2) that
the C99 _Bool type also has size 1.
config HAVE_CXX
bool "Have C++ compiler"
default n
---help---
Toolchain supports C++ and CXX, CXXFLAGS, and COMPILEXX have been
defined in the configurations Make.defs file.
if HAVE_CXX
choice
prompt "C++ Library"
default NUTTX_LIBXX
config NUTTX_LIBXX
bool "NuttX C++ library"
---help---
A fragmentary C++ library that will allow to build only
the simplest of C++ applications. In the deeply embedded world,
that is probably all that is necessary.
config LIBCXX
bool "LLVM libc++ C++ Standard Library"
select CLOCK_MONOTONIC
select LIBC_WCHAR
select LIBC_LOCALE
---help---
LLVM "libc++" C++ Standard Library

config UCLIBCXX
bool "uClibc++ Standard C++ Library"
---help---
uClibc++ C++ library
https://cxx.uclibc.org/

config HAVE_CXXINITIALIZE
bool "Have C++ initialization"
default LIBCXX || UCLIBCXX
---help---
The platform-specific logic includes support for initialization
of static C++ instances for this architecture and for the selected
toolchain (via up_cxxinitialize()).
config CXX_EXCEPTION
bool "Enable Exception Support"
default LIBCXX || UCLIBCXX
config CXX_LIBSUPCXX
bool "Have libsupc++ (required)"
default LIBCXX || UCLIBCXX
---help---
Select if your toolchain provides libsupc++. This option is required
at present because the built-in libsupc++ support is incomplete.
if UCLIBCXX
config UCLIBCXX_BUFSIZE
int "IO Stream/Container Buffer Size"
default 32
