Workaround for gcc bug 68485 doesn't work anymore since bump to version
3.21 in commit 5b3e72139952e0c953c8649cca55571cec5f3836 because CXXFLAGS
is appended after CFLAGS and does not contain -O0:

/tmp/instance-7/output-1/host/bin/microblazeel-linux-gcc -o rtcm2_json.os -c --sysroot=/tmp/instance-7/output-1/host/microblazeel-buildroot-linux-uclibc/sysroot -pthread -Wall -Wcast-align -Wextra -Wimplicit-fallthrough -Wmissing-declarations -Wmissing-prototypes -Wno-missing-field-initializers -Wno-uninitialized -Wpointer-arith -Wreturn-type -Wstrict-prototypes -Wvla -O0 -Os -g0 -pthread -fPIC -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -I/tmp/instance-7/output-1/host/microblazeel-buildroot-linux-uclibc/sysroot/usr/include/dbus-1.0 -I/tmp/instance-7/output-1/host/microblazeel-buildroot-linux-uclibc/sysroot/usr/lib/dbus-1.0/include rtcm2_json.c
during RTL pass: reload
rtcm2_json.c: In function ‘json_rtcm2_read’:
rtcm2_json.c:267:1: internal compiler error: in gen_reg_rtx, at emit-rtl.c:1155
  267 | }
      | ^

It should be noted that GPSD_CXXFLAGS was added 5 years ago with commit
b4c050e9afed7a8dc302e6e1014cc4ffb508590d but was not actually used in
that commit or any later.
