gdb: LoongArch: fix failed testcases in gdb.base/align-c.exp

Browse Source 
When execute the following command on LoongArch:

  make check-gdb TESTS="gdb.base/align-c.exp"

there exist some failed testcases:

  ...
  FAIL: gdb.base/align-c.exp: print _Alignof(struct align_pair_long_double_x_float)
  FAIL: gdb.base/align-c.exp: print _Alignof(struct align_pair_long_double_x_double)
  FAIL: gdb.base/align-c.exp: print _Alignof(struct align_pair_long_double_x_long_double)
  ...

According to LoongArch ELF ABI specification [1], set the target data types
of floating-point to fix the above failed testcases.
