[tlbuild] --host is not passed to ICU

[Mojca Miklavec]

Hi,

I tried to cross-compile TL with some of the flags that I have
shamelessly "stolen" from LuaTeX's build script (not sure if those
C[XX]FLAGS actually make sense):

NAME=x86_64-w64-mingw32
export CC=${NAME}-gcc
export CXX=${NAME}-g++
export RANLIB=${NAME}-ranlib
export STRIP=${NAME}-strip
export CFLAGS="-mtune=nocona -g -O3 -fno-lto -fno-use-linker-plugin ${CFLAGS}"
export CXXFLAGS="-mtune=nocona -g -O3 -fno-lto -fno-use-linker-plugin
${CXXFLAGS}"
export LDFLAGS="${LDFLAGS} -fno-lto -fno-use-linker-plugin
-static-libgcc -static-libstdc++"

./Build -C --host=${NAME} --build=x86_64-apple-darwin

but the build fails because --host does not proliferate to icu-native
(it does reach configuration of other libraries though).
