What is the Uniform Name to build program with PIC?

[Jeffrey Walton]

I'm having this problem on 32-bit ARM:

Our bin_* recipe looks like this:

bin_PROGRAMS = cryptest

cryptest_CXXFLAGS = $(AM_CXXFLAGS)
cryptest_SOURCES = \
    test.cpp bench1.cpp bench2.cpp \
    validat1.cpp validat2.cpp validat3.cpp

cryptest_LDADD = $(lib_LTLIBRARIES)

I think I need one of those uniform names that tell the machinery to
build the program with PIC like the library (lib_LTLIBRARIES). I don't
see the option at
https://www.gnu.org/software/automake/manual/automake.html#Uniform .
