  Not from 'make foo_defconfig', but from 'make menuconfig'.

  If in the buildroot config I select 'Use omap2plus defconfig' for the 
kernel, then I expect it to use the omap2plus configuration. Similarly, 
if I set the custom linux config to /some/path/linux.config, then I 
expect that that configuration will be used.

  So 'configured' is what you see in 'make menuconfig', 'customized' is 
what you see in 'make linux-menuconfig'.

  But the problem is that the buildroot configuration conflicts with the 
kernel configuration.
