For reference, the solution is:

# pkg -o PKG_ENV=envvar1=value1,envvar2=value2,... command

So, in my case:

# pkg -o PKG_ENV=http_proxy= update

While I've tried it before, I failed to have it work because, when used 
in combination with the '-o' option, PKG_ENV *must* be spelled 

In order to set an environment variable to the null value, you have to 
put it at the end:

# pkg -o PKG_ENV=empty=,valued=1 config pkg_env
empty: ,valued=1
valued: 1

It seems there's no way to null more than one variable at once (but I 
could have misread the source).
