I've improved the patch a bit and I think it should work in most places we
build
things now. Patch is on the list.

I think we should disable building pseudo for targets which are not used as
build hosts so essentially your patch is good with another addition of
compatible host string

I think that would be an issue with my patch in master-next to try and fix
other pseudo issues with 2.34 hosts.
Basically we need pseudo to work with older glibc where the dlsym/dlvsym/dlerror
functions are in libdl. This is because libpseudo may be loaded against host
binaries
which were not linked with glibc 2.34 but something older.
To do that, we need to inject older versioning but the version to use is arch
specific. I have a patch covering 32/64 bit x86 and arm but I haven't got
further
than that:
++#if defined (__aarch64__)
++#define DLSYMVER "2.17"
++#define DLSYMVER2 "2.17"
++#elif defined(__i386__)
++#define DLSYMVER "2.0"
++#define DLSYMVER2 "2.1"
++#else
++#define DLSYMVER "2.2.5"
++#define DLSYMVER2 "2.2.5"
++#endif
++
++__asm__(".symver dlerror,dlerror@GLIBC_" DLSYMVER);
++__asm__(".symver dlvsym,dlvsym@GLIBC_" DLSYMVER2);
++__asm__(".symver dlsym,dlsym@GLIBC_" DLSYMVER);
I may need help finishing this off for other arches people are building it for.
So far
I was using this as a test to see if this would even work!
Cheers,
Richard

[OE-core] [PATCH] glibc: package the stub .a libaries into glibc-dev
In glibc 2.34, the libraries libpthread, libdl, libutil, libanl have
been integrated into libc. To retain compatibility with old binaries the
shared libaries are still shipped but are empty, and to keep software
building there are empty static libraries.
However, these static libraries get packaged into glibc-staticdev (as
they should be), but by this design they should be in glibc-dev.
