Work around gcc10 FAIL: S-records with constructors
gcc10 on x86_64 and powerpc64le recognises that the loop in
Foo::operator= can be turned into a call to memmove, which then
results in an undefined symbol when linking. Avoid that by making the
loop smaller.
* testsuite/ld-srec/sr3.cc (FOO_MSG_LEN): Set to 4.
