[OE-core] [PATCH 1/1] eglibc: tweak glibc.fix_sqrt2.patch for eglibc-2.19

[Hongxu Jia]

While the type of powerpc32 cpu is 603e (In meta/conf/machine/
qemuppc.conf, require conf/machine/include/tune-ppc603e.inc),
there was a failure to build eglibc-2.19:
...
| ../sysdeps/powerpc/powerpc32/603e/fpu/e_sqrt.c: In function
'__slow_ieee754_sqrt':
| ../sysdeps/powerpc/powerpc32/603e/fpu/e_sqrt.c:122:15: error:
subscripted value is neither array nor pointer nor vector
|        if ((u.l[1] & FE_INVALID) == 0)
|                ^
| ../sysdeps/powerpc/powerpc32/603e/fpu/e_sqrt.c:121:20: warning:
variable 'u' set but not used [-Wunused-but-set-variable]
|        fenv_union_t u = { .fenv = fegetenv_register () };
...

In 'eglibc-2.19/libc/sysdeps/powerpc/fpu/fenv_libc.h', the above
struct fenv_union_t is defined as:
...
typedef union
{
  fenv_t fenv;
  unsigned long long l;
} fenv_union_t;
...

Rather than 'eglibc-2.16/libc/sysdeps/powerpc/fpu/fenv_libc.h':
...
typedef union
{
  fenv_t fenv;
  unsigned int l[2];
} fenv_union_t;
...

So we should update the glibc.fix_sqrt2.patch for eglibc-2.19.
