You can run bjam with --debug-configuration and look for:
bash -c "g++ -ltcmalloc_minimal -x c++ - <<<'int main() {}' -o
/home/kpu/mosesdecoder/dummy >/dev/null 2>/dev/null && rm
/home/kpu/mosesdecoder/dummy 2>/dev/null"
The next line is the return code. If it's 0, then tcmalloc_minimal will
be linked in. Or run with -d2 and look for -ltcmalloc_minimal in the
linker command line.
