Thing is that I don't see how the gtk2_atk_adaptor option pointed by
Daniel Lang can help, and how it relates to dlopen() being needed or
not.

Indeed, in meson.build, regardless of gtk2_atk_adaptor, I see:

if not get_option('atk_only')
  if cc.has_function('dlopen')
    dl_dep = []
  elif cc.has_function('dlopen', args: '-ldl')
    dl_dep = cc.find_library('dl')
  else
    error('Could not find a library with the dlopen function')
  endif
endif

so unless atk_only is defined, dlopen() will be needed. atk_only is
defined as such:

option('atk_only',
       description: 'Build only the ATK stub library without atspi or at-spi2-atk (UNSUPPORTED)',
       type: 'boolean',
       value: false)

of course the UNSUPPORTED is a bit scary. But perhaps that would make
sense in the context of Buildroot. Both libgtk2/libgtk3 require
at-spi2-core, but we can imagine that real accessibility support is not
always needed, so being able to build a stub at-spi2-core might be
interesting, and that would allow to not require dlopen(), apparently.
