Details:

While trying to package Buildprogram in Conda, BuildProgram's test in `make
check' failed for macOS. This is because the conda environment highly
configures the linking of standard builds on macOS as shown below:


LDFLAGS=-Wl,-pie -Wl,-headerpad_max_install_names -Wl,-dead_strip_dylibs
-Wl,-rpath,$PREFIX/lib -L$PREFIX/lib


But because of failures with special flags on other systems (see bug #54346),
BuildProgram only keeps the `-L' options from the input `LDFLAGS' environment
in its configuration file. 

To fix this problem, and generally, give the users the ability to control the
build better, BuildProgram also needs to include the LDFLAGS and CPPFLAGS
environment variables.
