Hey Boost,
I am trying to build Boost, ideally in its entirety, with emscripten.  I am
using emscripten 1.38.8, and either Boost 1.67 or the 1.68.b1, and am on
OSX 10.13.  Both Boost versions fail.

I bootstrapped as normal (`./bootstrap.sh`), and then invoke b2 to build.
i want C++14, so invoke as

./b2 toolset=emscripten cxxflags=-std=c++14

I get this long message with the roadblock at the end:

Performing configuration checks

    - default address-model    : 32-bit
    - default architecture     : none

Building the Boost C++ Libraries.

    - symlinks supported       : yes

*Error: ambiguity found when searching for best transformation*
*Trying to produce type 'SEARCHED_LIB' from: *
*Generators that succeeded:*
* -  searched-lib-generator*
* -  emscripten.searched-lib-generator*
*First generator produced: *
* -  { %.no-action-icudata.SEARCHED_LIB }*
*Second generator produced: *
* -  { %.no-action-icudata.SEARCHED_LIB }*

I can get past this error by disabling icu, with

./b2 toolset=emscripten cxxflags=-std=c++14 --disable-icu

but i just get a similar error.

*Error: ambiguity found when searching for best transformation*
*Trying to produce type 'SEARCHED_LIB' from: *
*Generators that succeeded:*
* -  searched-lib-generator*
* -  emscripten.searched-lib-generator*
*First generator produced: *
* -  { %.no-action-z.SEARCHED_LIB }*
*Second generator produced: *
* -  { %.no-action-z.SEARCHED_LIB }*

of course, using c++14 doesn't affect my problem whatsoever.

can anybody help me?
