There's a funny thing, though.
Command that built in example tidy.so was :

so theoretically it should not have those dependencies, unless
--preserve-dup-deps messes that up. I think I'll test this theory.
Of course, this is a completely separate issue to the one this bug is
about.

And we're not trying to fix the faulty 3rd party libraries here, are
we? :)

I have tested it with some extensions and seem to work fine, except
that the IMAP extension does not compile because configure checks fail
for the same reason the reporter is showing here.

although in most cases the guilty stuff is "foobar_config" scripts or
pkgconfig scripts that inject "uneeded" dependencies (uneeded at least
on linux)

After some investigation to this flag I'm leaning towards simply
filtering it out totally if someone tries to use it. Reasons being:
a) it seems to be experimental
b) might cause problems in dynamic loading such as our shared
extensions, f.e. php -> pdo -> pdo driver (haven't tested yet :)
c) requires that pretty much everything in the system has to be
compiled using it
d) PHP build system does not link with anything else than what is
actually needed anyway (AFAIK)

For a simple test case:
#include <glib.h>
int main()
{
g_print("test done\n");
return 0;
}
gcc -o minitest -Wl,--as-needed `pkg-config glib-2.0 --cflags`
minitest.c `pkg-config glib-2.0 --libs`
- compiles fine
gcc -o minitest -Wl,--as-needed `pkg-config glib-2.0 --cflags`
`pkg-config glib-2.0 --libs` minitest.c
- gives
/tmp/ccKZrHDW.o: In function `main':
minitest.c:(.text+0x19): undefined reference to `g_print'
collect2: ld returned 1 exit status
