gdb 8.2 static link version

Dear sir:

i tried to build gdb in ubuntu 18.04 static version with below warning 
message for X86_64. I need to put them in my android phone.

I added all so lib with related .a file. I got some warning message as 
below and no gdb file create.

how could I solve those warning to produce a gdb exec file ? or there 
are better ways to make static linked version ?

thanks a lot

Yu
