Description jonys 2024-03-16 11:32:07 UTC 
When compiling dev-libs/nss-3.91 for powerpc-gentoo-linux-musl, the build fails with
```
powerpc-gentoo-linux-musl-gcc  -shared  -Wl,--gc-sections -Wl,-z,defs -Wl,-soname -Wl,libfreebl3.so  -Wl,--version-script,Linux6.6_ppc_powerpc-gentoo-linux-musl-gcc_glibc_PTH_OPT.OBJ/Linux_SINGLE_SHLIB/freebl.def -Wl,-Bsymbolic -Wl,-O1 -Wl,--as-needed  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack  -z noexecstack -o Linux6.6_ppc_powerpc-gentoo-linux-musl-gcc_glibc_PTH_OPT.OBJ/Linux_SINGLE_SHLIB/libfreebl3.so Linux6.6_ppc_powerpc-gentoo-linux-musl-gcc_glibc_PTH_OPT.OBJ/Linux_SINGLE_SHLIB/lowhash_vector.o      -ldl -lc

```

The function PR_SetError is part of nspr (specifically, libnspr4.so), but the linker command in question doesn't link it. Passing LDFLAGS='-lnspr4' to emerge doesn't work around the problem, because strip-flags removes it before the build starts.

Commenting out the single function call responsible for the error does work, see the patch in https://lore.kernel.org/all/20240112192003.1004726-1-fontaine.fabrice@gmail.com/T/ (and the associated thread). The message also indicates that the error might not be specific to powerpc (I have no other musl systems to confirm this).

Reproducible: Always
