    Fix 32-bit x86 in-process agent build
    
    Git commit 3c14e5a39bb4fddd added a declaration for
    gdb_agent_get_raw_reg to tracepoint.h, and this now caught that the
    32-bit x86 implementation has the wrong prototype:
    
     ../../../src/gdb/gdbserver/linux-i386-ipa.c:103:1: error: conflicting types for ‘gdb_agent_get_raw_reg’
      gdb_agent_get_raw_reg (unsigned char *raw_regs, int regnum)
      ^
     In file included from ../../../src/gdb/gdbserver/linux-i386-ipa.c:24:0:
     ../../../src/gdb/gdbserver/tracepoint.h:168:31: note: previous declaration of ‘gdb_agent_get_raw_reg’ was here
