[Buildroot] [git commit branch/next] package/zmqpp: don't set CONFIG=debug

commit: https://git.buildroot.net/buildroot/commit/?id=47c26b3e5fcda164ffdf6b9e4be8057367203af9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Below are the flags set by zmqpp depending on the specified CONFIG variable:

CONFIG_FLAGS =
ifeq ($(CONFIG),debug)
        CONFIG_FLAGS = -g -fno-inline -ftemplate-depth-1000
endif
ifeq ($(CONFIG),valgrind)
        CONFIG_FLAGS = -g -O1 -DNO_DEBUG_LOG -DNO_TRACE_LOG
endif
ifeq ($(CONFIG),max)
        CONFIG_FLAGS = -O3 -funroll-loops -ffast-math -finline-functions \
            -fomit-frame-pointer -DNDEBUG
endif
ifneq (,$(findstring $(CONFIG),release loadtest))
        CONFIG_FLAGS = -O3 -funroll-loops -ffast-math -finline-functions \
            -fomit-frame-pointer -DNO_DEBUG_LOG -DNO_TRACE_LOG -DNDEBUG
endif

For the flags added with CONFIG=debug, '-g' is to be steered by the core
infrastructure (could be '-g1', '-g2' etc.)
The flag '-ftemplate-depth' is only a protection against incorrect code and
not really needed in Buildroot context.
Finally, the flag '-fno-inline' may be useful when really stepping through
zmqpp code, but is a very specific use case.

With the above in mind, not passing CONFIG=debug may actually be better.
Use 'CONFIG=buildroot' instead.

Note that we don't pass an empty 'CONFIG' to avoid confusion, as this
variable is also passed through to the variable BUILD_ENV, even though it is
currently unused.
