The `file->bytevector' new procedure uses a memory mapped bytevector, so
parsing the ELF file reads only the sections needed, not the whole file.

* guix/scripts/pack.scm (wrapped-package): Use file->bytevector.
* guix/build/gremlin.scm (file-dynamic-info): Likewise.
(validate-needed-in-runpath): Likewise.
(strip-runpath): Likewise, and write to bytevector directly, avoiding a port.
(set-file-runpath): Likewise.
* tests/gremlin.scm (read-elf): Delete procedure.
("elf-dynamic-info-needed, executable"): Use file-dynamic-info.
("strip-runpath"): Likewise.
("elf-dynamic-info-soname"): Likewise.
 guix/build/debug-link.scm (set-debuglink-crc): Use file->bytevector.
* tests/debug-link.scm (read-elf): Delete procedure.
("elf-debuglink"): Rename to...
("elf-debuglink, no .gnu_debuglink section"): ... this.
("elf-debuglink", "set-debuglink-crc"): Use external store, and adjust to use
file->bytevector.
* gnu/packages/gnuzilla.scm (icecat-minimal) [#:phases]
{build-sandbox-whitelist}: Use `file-runpath'.
* gnu/packages/librewolf.scm (librewolf): Likewise.

* tests/gremlin.scm: Include stdio.h before using puts since GCC 14 no
longer allows implicit declarations.

Fixes: <https://issues.guix.gnu.org/52943>.

* tests/gremlin.scm (file-needed/recursive)[ground-truth]: On aarch64-linux,
remove the dynamic linker from this list.

Fixes <https://issues.guix.gnu.org/52752>.
Reported by Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org>.

* tests/gremlin.scm ("file-needed/recursive"): Augment the list of vDSO
names.

Fixes: <https://issues.guix.gnu.org/52940>.

* tests/gremlin.scm (file-needed/recursive): Consider two entries to be
equivalent not when they are the same string, but rather when they refer to
the same file.
[ground-truth]: In addition to strings that begin with "linux-vdso.so", remove
strings that begin with "linux-vdso64.so".

* tests/gremlin.scm (file-needed/recursive): Skip the test when (file-runpath
%guile-executable) evaluates to the empty list.  This causes the test to be
correctly skipped in the case where Guix has been built using a foreign
distro's toolchain and libraries.

* guix/build/gremlin.scm (elf-dynamic-info): Return the dynamic entry
value, not the dynamic entry.
* tests/gremlin.scm ("elf-dynamic-info-soname"): New test.
