Impossible to link with python (compiled with pymalloc)

Hi all,

Today I'm using a configuration like that:

```
using python : 3.4
: /build/bin/python3.4
: /build/include/python3.4m
: /build/lib
;
```

The problem lies in the fact that the library is `libpython3.4m.a` and Boost.Build is completely ignoring the `m` suffix:

```
"g++" -dynamiclib -Wl,-single_module -install_name "libboost_python3.dylib" -L"/Users/Xcloud/sandbox/8cube/build/lib" -o "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/libboost_python3.dylib" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/numeric.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/list.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/long.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/dict.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/tuple.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/str.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/slice.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/converter/from_python.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/converter/registry.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/converter/type_id.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/enum.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/class.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/function.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/inheritance.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/life_support.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/pickle_support.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/errors.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/module.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/converter/builtin_converters.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/converter/arg_to_python_base.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/iterator.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/stl_iterator.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object_protocol.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object_operators.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/wrapper.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/import.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/exec.o" "bin.v2/libs/python/build/darwin-4.2.1/release/threading-multi/object/function_doc_signature.o" -lpython3.4 -headerpad_max_install_names -Wl,-dead_strip -no_dead_strip_inits_and_terms

ld: library not found for -lpython3.4
```

If I execute

```
/build/bin/python3.4 -c 'import distutils.sysconfig as s; print(s.get_config_var("LIBRARY"))'
```

it prints the correct library filename.

Also, I tried to specify the `3.4m` version instead of `3.4` but it does nothing more than warn me about it:

```
Warning: "using python" expects a two part (major, minor) version number; got 3.4m instead
```

Does anybody know how to link with python when it as been compiled with pymalloc ?
Is there a workaround not involving a symlink ?
