testsuite: Adjust fam-in-union-alone-in-struct-2.c to support BE [PR116148]
As Andrew pointed out in PR116148, fam-in-union-alone-in-struct-2.c
was designed for little-endian, the recent commit r15-2403 made it
be tested with running on BE and PR116148 got exposed.
This patch is to adjust the expected data for members in with_fam_2_v
and with_fam_3_v by considering endianness, also update with_fam_3_v.b[1]
from 0x5f6f7f7f to 0x5f6f7f8f to avoid two "7f"s.
PR testsuite/116148
gcc/testsuite/ChangeLog:
* c-c++-common/fam-in-union-alone-in-struct-2.c: Define macros
WITH_FAM_2_V_B[03] and WITH_FAM_3_V_A[07] as endianness, update the
checking with these macros and initialize with_fam_3_v.b[1] with
0x5f6f7f8f instead of 0x5f6f7f7f.
