I confirmed I didn't include -fno-omit-frame-pointer, but I find I
have -fno-omit-frame-pointer in MPS_CFLAGS:

```bash
$ cat config.log | grep -C3 fno-omit-frame
MODULES_OBJ='emacs-module.o'
MODULES_SECONDARY_SUFFIX=''
MODULES_SUFFIX='.so'
MPS_CFLAGS='-fno-omit-frame-pointer'
NANOSLEEP_LIB=''
NATIVE_COMPILATION_AOT='yes'
NDK_BUILD_ABI=''
```

And I build emacs by:

#!/usr/bin/env bash
set -ex

make extraclean

BRANCH_NAME=$(git branch --show-current | sed 's/\//_/g')
COMMIT_ID=$(git rev-parse HEAD)
BUILD_DIR=${BRANCH_NAME}-${COMMIT_ID}-pgtk-gdb
INSTALL_PREFIX=$(realpath ../emacs-build/${BUILD_DIR})

./autogen.sh
./configure  CFLAGS='-g3 -ggdb -O3 -march=native' \
  --prefix=${INSTALL_PREFIX} \
  --with-imagemagick  \
  --with-mps=yes \
  --with-pgtk \
  --with-modules \
  --with-cairo --with-cairo-xcb \
  --without-compress-install \
  --with-mailutils\
  --enable-link-time-optimization \
  --with-tree-sitter --with-xinput2 \
  --with-dbus \
  --with-native-compilation=aot \
  --with-file-notification=inotify\
  && make -j20 install
