bug#73979: validate-runpath phases fails when binaries linked to package's own libraries

[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

Hi,

There's a common pattern in packages where the validate-runpath phases
fail, which is when a binary is linked to libraries provided by the same
package.  In this case, our ld-wrapper script appears to not bake the
required runpath, which then fails the validate-runpath phase.

When this happens, the common workaround is adding link directives such
as (string-append "-Wl,-rpath=" #$output "/lib/subdir") to LDFLAGS (see
for example the 'dmraid' package definition).

Here's a recent example, attempting to build TORCS:

So we see that ld-wrapper saw the accc-bin binary being linked against
the package's own
/tmp/guix-build-torcs-1.3.7.drv-0/torcs-1.3.7/export/lib/libtgf.so, but
this is later dismissed for "not being in the store", by this code in
gnu/packages/ld-wrapper.in:

--8<---------------cut here---------------start------------->8---
(define (rpath-arguments library-files)
  ;; Return the `-rpath' argument list for each of LIBRARY-FILES, a list of
  ;; absolute file names.
  (fold-right (lambda (file args)
                ;; Add '-rpath' if and only if FILE is in the store; we don't
                ;; want to add '-rpath' for files under %BUILD-DIRECTORY or
                ;; %TEMPORARY-DIRECTORY because that could leak to installed
                ;; files.
                (cond ((and (not %disable-rpath?)
                            (store-file-name? file))
                       (cons* "-rpath" (dirname file) args))
                      ((or %allow-impurities?
                           (pure-file-name? file))
                       args)
                      (else
                       (begin
                         (format (current-error-port)
                                 "ld-wrapper: error: attempt to use \

                                 %store-directory file)
                         (exit 1)))))
              '()
              library-files))
--8<---------------cut here---------------end--------------->8---

(pure-file-name? x) returns #t (it considers build directory files as
"pure"), but the args is not augmented with -rpath in this case, so the
link directives are simply skipped.

One idea could be to allow creating rpaths to %BUILD-DIRECTORY prefixed
libraries, and have these entries refined in a phase that would run
after the package is installed, before the validate-runpath phase runs.
It could be called e.g. 'sanitize-runpath' and proceed along those
lines:

Scan for RUNPATH entries being prefixed by %BUILD-DIRECTORY; attempt to
have them rewritten to libraries (.so) found under the package's own
libdir library prefix (at any depth), including a potential "lib"
output.  In case it couldn't, it would error.

Does that sound feasible?
