[Bug 1923361] [NEW] unable to link xdr functions with groovy and hirsute

[Dominique Rousset]

Public bug reported:

Hi,
I have a technical code that relies on XDR for it's internal data format. I cannot compile it anymore with hirsute (and groovy).

As a simpler test I tried to compile

#include <rpc/xdr.h>
int main(){
xdr_void();
}

called it testxdr.c 
gcc -o testxdr -I/usr/include/tirpc -ltirpc testxdr.c

-I and -l options are indicated by package-config.

With the include compilation is OK but the linking fails with an indefinite reference to xdr_void.
With focal, nor -I neither -l options are necessary, xdr functions are within glibc. 
With hirsute nm says that xdr_void symbol is defined in libtirpc.so and surprisingly (for me) in glibc 2.33 (should have been removed since 2.32 ?)

Any help is welcome !

D.
