package/apcupsd: set LD to TARGET_CXX

Browse Source 
As found out by Yann E. Morin in [1], apcupsd configure script is ugly,
and uses gcc to do the link line-wrapping which will raise the following
build failure with gcc 13:

/home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/powerpc64le-buildroot-linux-gnu/13.2.0/../../../../powerpc64le-buildroot-linux-gnu/bin/ld: /home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/powerpc64le-buildroot-linux-gnu/13.2.0/../../../../powerpc64le-buildroot-linux-gnu/lib/../lib64/libsupc++.a(eh_alloc.o): in function `std::basic_string_view<char, std::char_traits<char> >::compare(unsigned long, unsigned long, char const*, unsigned long) const':
eh_alloc.cc:(.text._ZNKSt17basic_string_viewIcSt11char_traitsIcEE7compareEmmPKcm[_ZNKSt17basic_string_viewIcSt11char_traitsIcEE7compareEmmPKcm]+0x44): undefined reference to `std::__throw_out_of_range_fmt(char const*, ...)'

It will also raise the following build failure on sparc/arc:

/home/autobuild/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arceb-snps-linux-uclibc/9.2.1/../../../../arceb-snps-linux-uclibc/bin/ld: /home/autobuild/autobuild/instance-3/output-1/host/arceb-buildroot-linux-uclibc/sysroot/lib/libsupc++.a(eh_throw.o): in function `__exchange_and_add_dispatch':

/home/autobuild/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arceb-snps-linux-uclibc/9.2.1/../../../../arceb-snps-linux-uclibc/bin/ld: /SCRATCH/arcjenkins2/slaves/ru20-custom-arcgnu2/workspace/arcoss_verification/arc_gnu_toolchain_release/arc_gnu_toolchain_release/bd-uclibceb/gcc-stage2/arceb-snps-linux-uclibc/libstdc++-v3/include/ext/atomicity.h:82: undefined reference to `__gnu_cxx::__exchange_and_add(int volatile*, int)'

Instead of trying to patch the configure script as advocated by
Yann E. Morin, set LD to TARGET_CXX as:
 - this solution is quicker
 - usptream is dead (last release in 2016)
 - this solution has already been used in other packages (nodejs, zmqpp)
