This is actually an issue in the dynamic linker (ld.so) affecting armhf 
since GCC 15 is used to build glibc. I have sent a patch upstream:
https://inbox.sourceware.org/libc-alpha/20260510220041.169362-1-aurelien@aurel32.net

I am therefore reassigning the bug to the glibc package. On the erfa 
side, the workarounds can be removed, it'll build fine once a fixed glibc 
reaches the archive.

Regards
Aurelien
