Compiling for linux/386 fails with missing header file

[gerricom]

Since the 4th of May my xgo builds for linux/386 are failing with this message:

Compiling for linux/386...
# runtime/cgo
In file included from _cgo_export.c:3:
/usr/include/stdlib.h:25:10: fatal error: bits/libc-header-start.h: No such file or directory
   25 | #include <bits/libc-header-start.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

I'm not very used on tracking down compiling errors so I kindly ask for some help. My little pipeline pulls the latest xgo image for every build and I guess something might have changed here? The commits tell me, that there were changes for arm64. Could that brought some unwanted side effects for 386 builds?
