Current trunk fails to build gmp

[Rainer Emrich]

Since some time in November last year trunk fails to build gmp.
Last successfull build was 30th of October last year.

The issue seems to be a failing configure test. From config.log:

Test compile: long long reliability test 1

conftest.c: In function 'f':

      |                                                ^ ~
conftest.c:7:6: note: declared here
    7 | void g(){}
      |      ^
configure:6588: $? = 1
failed program was:

   1666 to segfault with e.g., -O2 -mpowerpc64.  */

#if defined (__GNUC__) && ! defined (__cplusplus)
typedef unsigned long long t1;typedef t1*t2;
void g(){}
void h(){}
static __inline__ t1 e(t2 rp,t2 up,int n,t1 v0)

for(i=0;i<1;i++){if(e(got,got,9,d[i].n)==0)h();g(i,d[i].src,d[i].n,got,d[i].want,9);if(d[i].n)h();}}
#else
int dummy;
#endif

int main () { return 0; }
configure:7072: result: no, long long reliability test 1

Any comments?

I can open a PR if neccessary.
