Atomic test does not work correctly #1
Description
Running the build on ppc (i.e. 32-bit), I get this:
---> Building R-qs2

Using TBB
Does not require -latomic flag
configure: creating ./config.status
config.status: creating src/Makevars
However, ppc requires -latomic in order to support 64-bit atomics.
Needless to say, in result Makevars do not get the flag:
PKG_CPPFLAGS=-DRCPP_USE_UNWIND_PROTECT -DRCPP_NO_RTTI -DRCPP_NO_SUGAR -I../inst/include -I. -DIS_UTF8_LOCALE=$(shell "${R_HOME}/bin/Rscript" -e "cat(as.integer(identical(utils::localeToCharset()[1], 'UTF-8')))")
PKG_CXXFLAGS = $(shell ${R_HOME}/bin/Rscript -e "RcppParallel::CxxFlags()")
PKG_LIBS = -L. -L/opt/local/lib -lzstd $(shell ${R_HOME}/bin/Rscript -e "RcppParallel::RcppParallelLibs()")
LIBZSTD = ZSTD/zstd.o
$(SHLIB):
libQSZSTD.a: $(LIBZSTD)
$(AR) rcs libQSZSTD.a $(LIBZSTD)
clean:
rm -f $(SHLIB) $(OBJECTS)
I am not sure why, but the test gives an inaccurate result.
