package/gpsd: fix workaround for gcc bug 68485

Browse Source 
Workaround for gcc bug 68485 doesn't work anymore since bump to version
3.21 in commit 5b3e721399 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
b4c050e9af but was not actually used in
that commit or any later.
