Yep, using a VPATH build with the source being a soft link does not
work. Here is what I have done, basically the same steps as yourself:
wget https://ftp.postgresql.org/pub/source/v15rc1/postgresql-15rc1.tar.gz
tar zxvf postgresql-15rc1.tar.gz
ln -s postgresql-15rc1 postgres_src
mkdir postgres_build
cd postgres_build/
$path/to/postgres_src/configure --prefix=$PGDIR/install --enable-cassert
make -j 4

This is as well the case with 14, by the way, and most likely the case
of older versions. Why are you using such an exotic way to build
things? A vpath build would give the same result for the build, once
the downloaded source is renamed to a more generic name, for example.
