Hm.  I can't replicate this at all.  I followed your recipe (except for
starting in ~/tmp not /usr/src) and the make completed without error.
I see

$ pwd
/home/tgl/tmp/postgresql-9.0.2
$ find . -name schemapg.h -ls
1984573   16 -rw-r--r--   1 tgl      tgl         14754 Dec 13 22:20 ./src/src/backend/catalog/schemapg.h
2097841    0 lrwxrwxrwx   1 tgl      tgl            65 Jan 29 18:25 ./obj-x86_64/src/include/catalog/schemapg.h ->
/home/tgl/tmp/postgresql-9.0.2/src/src/backend/catalog/schemapg.h

As you can see, the symlink has the correct absolute path to the
schemapg.h file in the source tree.  You're getting a wrong link:

> lrwxrwxrwx   1 dylan    src            68 Jan 29 06:38 ./obj-x86_64/src/include/catalog/schemapg.h ->
/loot/src/postgresql-9.0.2/obj-x86_64/src/backend/catalog/schemapg.h

I'm not sure about the "/loot" part (copy and paste-o?) but anyway it
seems to be pointing into the build tree not the source tree.

>> make -v
>> GNU Make 3.82

Mine is 3.81 (Fedora 13).  Is it possible this is a bug introduced in
3.82?  The symlink is made this way:

$(top_builddir)/src/include/catalog/schemapg.h: catalog/schemapg.h
    prereqdir=`cd $(dir $<) >/dev/null && pwd` && \
      cd $(dir $@) && rm -f $(notdir $@) && \
      $(LN_S) "$$prereqdir/$(notdir $<)" .

so AFAICS the possibilities are that make is getting the wrong answer
for "dir $<" or that pwd is broken.

What platform are you on exactly?
