I'm not sure if it's this change that breaks the build
or if it was always broken but:

Notice the complete lack of -lpcre in that line --
it only appeared after I added LIBS=-lpcre to ./configure.
I think something's wonky.

Not really: you'll find "-lpcre -export-dynamic server/libmain.la"
somewhere in the middle of the line.
But pcre being linked before libmain should be the problem. My linker
didn't complain, but yours obviously does.
Should be fixed in r1142893.
Thanks for testing!

Not necessary.

Right, it was :)
