Previously setup.py splits compiler flags by a single whitespace, which causes build failures when there are two space characters, causing an extra empty string being added to the compiler command line.

In my case, polymake-config --cflags returned a string with two space characters before the last compiler flag:

-DPOLYMAKE_VERSION=409 -fPIC -pipe -march=rv64gc -mabi=lp64d -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -Wp,-D_GLIBCXX_ASSERTIONS -g -ffile-prefix-map=/build/polymake/src=/usr/src/debug/polymake -flto=auto -std=c++14 -ftemplate-depth-200 -fno-strict-aliasing -fopenmp -Wshadow -Wlogical-op -Wconversion -Wzero-as-null-pointer-constant -Wno-parentheses -Wno-error=unused-function -Wno-stringop-overflow -Wno-array-bounds -Wno-maybe-uninitialized -Wno-free-nonheap-object -DPOLYMAKE_WITH_FLINT  -DPOLYMAKE_DEBUG=0

An extra empty string got passed to the compiler and it caused a cryptic error.

g++: warning: : linker input file unused because linking not done
g++: error: : linker input file not found: No such file or directory

Previously setup.py splits compiler flags by a single whitespace,
which causes build failures when there are two space characters causing
an extra empty string being added to the compiler command line.
