Colons added after library names in LIBS (autotools build) #4074
Description
Here's a weird issue I'm getting with the current draft of the spack package on Ubuntu 24.04:
checking for Fortran libraries of /opt/spack/opt/spack/linux-zen2/compiler-wrapper-1.0-cpbsuow6nma4ib5tcxdpqkl3m2dkxher/libexec/spack/gcc/gfortran... -L/usr/lib/gcc/x86_64-linux-gnu/13 -L/usr/lib/gcc/x86_64-linux-gnu/13/../../../x86_64-linux-gnu -L/usr/lib/gcc/x86_64-linux-gnu/13/../../../../lib -L/lib/x86_64-linux-gnu -L/lib/../lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/13/../../.. -lglpk -lmps -lmpfi -lmpfr -lgmpxx -lgmp -lgc -lgdbm -lgfortran -lm -lquadmath -lglpk: -lmps: -lmpfi: -lmpfr: -lgmpxx: -lgmp: -lgc: -lgdbm:
In particular, it ends with -lglpk: -lmps: -lmpfi: -lmpfr: -lgmpxx: -lgmp: -lgc: -lgdbm:. Where did those colons come from? And of course, the build fails as soon as configure tries to link something because these libraries don't exist.
