--enable-application=browser is default, see configure.in

  MOZ_ARG_ENABLE_STRING(application,
  [...],
  [ MOZ_BUILD_APP=$enableval ] )
  ...
  if test -z "$MOZ_BUILD_APP"; then
    MOZ_BUILD_APP=browser
  else
  ...

Maybe try to apply patches listed in the upstream bugs quoted above.

Firefox builds everything with "hidden" visibility then explicitly
allowed headers are restored to "default" one[1]. It's a frequent source of
either linking or compilation issues. In desperate times you can jump on
OS X bandwagon by changing Darwin) to Darwin|FreeBSD) in the following

  $ cat configure.in
  ...
  if test "$GNU_CC" -a "$OS_TARGET" != WINNT; then
    case "$OS_TARGET" in
    Darwin)
      VISIBILITY_FLAGS='-fvisibility=hidden -fvisibility-inlines-hidden'
      ;;
    *)
      VISIBILITY_FLAGS='-I$(DIST)/system_wrappers -include $(MOZILLA_DIR)/config/gcc_hidden.h'
      WRAP_SYSTEM_INCLUDES=1
      ;;
    esac
  fi         # GNU_CC
