Ahh ok, good. As far as I can see, the uClibc fenv support is not really
extensive enough to ever work, so simply detecting uClibc should be
enough. Remember we can use uClibc through
internal/external/crosstool-ng toolchains, so you'll need to do
something like

ifeq ($(BR2_TOOLCHAIN_BUILDROOT)$(BR2_TOOLCHAIN_EXTERNAL_UCLIBC)$(BR2_TOOLCHAIN_CTNG_uClibc),y)
POCO_CONF_OPT += --no-fpenvironment
endif
