We also need to compile rsp-low.c for IPA, and link rsp-low-ipa.o
in IPA.  I get the ipa build error below,

gcc -shared -fPIC -Wl,--no-undefined -g -O2    -I. -I../../../../git/gdb/gdbserver -I../../../../git/gdb/gdbserver/../common -I../../../../git/gdb/gdbserver/../regformats -I../../../../git/gdb/gdbserver/.. -I../../../../git/gdb/gdbserver/../../include -I../../../../git/gdb/gdbserver/../gnulib/import -Ibuild-gnulib-gdbserver/import -Wall -Wdeclaration-after-statement -Wpointer-arith -Wformat-nonliteral -Wno-char-subscripts -Wempty-body -Werror -DGDBSERVER \

The fix is to compile rsp-low and link it with ipa, as below.
The compile error is fixed.
