libstdc++: Workaround glibc headers on ia64-linux
We see:
```
FAIL: 17_intro/names.cc -std=gnu++17 (test for excess errors)
FAIL: 17_intro/names_pstl.cc -std=gnu++17 (test for excess errors)
FAIL: experimental/names.cc -std=gnu++17 (test for excess errors)
```
...on ia64-linux.
This is due to:
* /usr/include/bits/sigcontext.h:32-38:
```
32 struct __ia64_fpreg
33 {
34 union
35 {
36 unsigned long bits[2];
37 } u;
38 } __attribute__ ((__aligned__ (16)));
```
* /usr/include/sys/ucontext.h:39-45:
```
39 struct __ia64_fpreg_mcontext
40 {
41 union
42 {
43 unsigned long __ctx(bits)[2];
44 } __ctx(u);
45 } __attribute__ ((__aligned__ (16)));
```
...from glibc 2.39 (w/ia64 support re-added). See the discussion
starting on [1].

libstdc++-v3/ChangeLog:

'u' as used in glibc headers.
