vasprintf is not present on Alpha or Itanium with RTL ECO v6 or earlier.
It only comes along with RTL ECO v9.  The only place I can find it
documented is in a special set of release notes that you get after
installation (or after rooting through the product kit):
SYS$HELP:VSI_OPENVMS_CRTL_ECO9_RELEASE_NOTES.TXT
Note that this is a supplement to the release notes that apply to the
whole kit and are separately downloadable ahead of time; those are named
something like VMS842L1A_RTL-V0900.RELEASE_NOTES.*
I do hope the new stuff gets into online help and the version dependency
tables in the CRTL manual at some point.
I have sent a pull request upstream to the FreeTDS maintainers with a
better detector for vasprintf:
https://github.com/FreeTDS/freetds/pull/660
I haven't had time yet to dig into why the replacement wasn't working.
