(Noticed last month when building a Docker suitable for gcc.)

Well aarch64 (arm64 [which is techincally not a thing]) defaults to having only one multi-lib (LP64) while x86_64 (amd64 which is the non-canonical name for x86_64) defaults to having both 64 and 32bit multi-lib.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41 --- Comment #3 from etienne_lorrain at yahoo dot fr --- Just reporting that the problem do not appears when --disable-multilib is asked at the configure stage. Unlike for ARM64 host compiling a native compiler, you need to say such --disable-multilib for amd64 compiling a native compiler.

--- Comment #2 from Andrew Pinski ---
I think we should improve the toplevel configure to error out if including
errno.h fails.
So instead of:
```
echo "int main () { return 0; }" > conftest.c
```
We should do:
```
echo "#include " > conftest.c
echo "int main () { return 0; }" >> conftest.c
```
I don't have a way to test this but this should at least cause the failure to
happen earlier during configure rather than later on.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41 --- Comment #1 from Jonathan Wakely --- Looks like you don't have the 32-bit headers installed. See https://gcc.gnu.org/wiki/FAQ#gnu_stubs-32.h
