LoongArch: Update ELF e_flags handling according to specification.
Update handling of e_flags according to the documentation
update [1] (discussions [2][3]).
Object file bitness is now represented in the EI_CLASS byte.
The e_flags field is now interpreted as follows:
e_flags[2:0]: Base ABI modifier
- 0x1: soft-float
- 0x2: single-precision hard-float
- 0x3: double-precision hard-float
e_flags[7:6]: ELF object ABI version
- 0x0: v0
- 0x1: v1
