Bug description:

Dear maintainers,

unfortunately, the fix of issue #116043 in Python 3.14 does not fix the problem at all. Now freeze.py adds dependencies to some Modules/_hacl/libHacl_Hash*.o files,
although their functionality is already contained in cpython. The result again ist that linking is not possible:

/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_Blake2s.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_Blake2b.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Lib_Memzero0.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_Blake2s_Simd128.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_Blake2b_Simd256.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_MD5.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_SHA1.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_SHA2.o: No such file or directory
/usr/bin/x86_64-linux-gnu-ld.bfd: cannot find Modules/_hacl/Hacl_Hash_SHA3.o: No such file or directory
collect2: error: ld returned 1 exit status

See attached error-log.txtfor the full compilation log. Thus, only again the crude hack creating all these files as empty files helps.

Here the steps to reproduce:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu Resolute Raccoon (development branch)
Release:        26.04

$ cat helloworld.py
#!/usr/bin/python3

import hashlib

print("Hello, World!")

m = hashlib.sha256()
#m = hashlib.sha3_224()
m.update(b"nobody inspects")
print(m.hexdigest())
$ /usr/share/doc/python3.14/examples/freeze/freeze.py -X setuptools -o frozen helloworld.py
$ cd frozen
$ make &> error_log.txt                              <-- see attachement to this issue

Research direction

Reproduce the failure with freeze.py using the helloworld.py and hashlib example, then inspect the generated frozen build and the Modules/_hacl object paths named in the linker errors. Compare the generated dependencies with the files available in the frozen tree. Done means make completes without manually creating empty HACL object files and the frozen executable runs successfully.
