I think it is. The funny bit is that it should be included in LDFLAGS by
default, on Linux. BSDI and some other operating systems need it too (at
least newer versions) and gave the same error with shared libraries if the
flag was omitted (old BSDI was COFF with fake-shared-libraries, new BSDI is
ELF)

I didn't bother to check, but does the embed Makefile include python's
Makefile* stuff from $prefix/config ? Does it contain -export-dynamic ? If
so, very pecurliar... ;-P
