On my system (GCC 10.2.0) it looks to me like the asm isn't required after
applying the other changes:

32-bit:

7b04dd60 <_GetCommandLineA at 0>:
7b04dd60:    a1 08 cc 0a 7b           mov    0x7b0acc08,%eax
7b04dd65:    c3                       ret    
7b04dd66:    8d b4 26 00 00 00 00     lea    0x0(%esi,%eiz,1),%esi
7b04dd6d:    8d 76 00                 lea    0x0(%esi),%esi

7b04dd70 <_GetCommandLineW at 0>:
7b04dd70:    a1 04 cc 0a 7b           mov    0x7b0acc04,%eax
7b04dd75:    c3                       ret    
7b04dd76:    8d b4 26 00 00 00 00     lea    0x0(%esi,%eiz,1),%esi
7b04dd7d:    8d 76 00                 lea    0x0(%esi),%esi

64-bit:

000000007b04fe40 <GetCommandLineA>:
    7b04fe40:    48 8b 05 09 a9 05 00     mov    0x5a909(%rip),%rax        #
7b0aa750 <command_lineA>
    7b04fe47:    c3                       retq   
    7b04fe48:    0f 1f 84 00 00 00 00     nopl   0x0(%rax,%rax,1)
    7b04fe4f:    00 

000000007b04fe50 <GetCommandLineW>:
    7b04fe50:    48 8b 05 f1 a8 05 00     mov    0x5a8f1(%rip),%rax        #
7b0aa748 <command_lineW>
    7b04fe57:    c3                       retq   
    7b04fe58:    0f 1f 84 00 00 00 00     nopl   0x0(%rax,%rax,1)

Perhaps this is due to the move to PE?
