Detecting some strange errors in installation of PETSc on centOS

Question

I met 2 problems when I build PETSc as follows:

1. ./configure --prefix=/home/lengjun/softwares/petsc_install
2. make PETSC_DIR=/home/lengjun/softwares/petsc-3.14.1 PETSC_ARCH=arch-linux2-c-debug all
3. make PETSC_DIR=/home/lengjun/softwares/petsc-3.14.1 PETSC_ARCH=arch-linux2-c-debug install
4. make PETSC_DIR=/home/lengjun/softwares/petsc_install PETSC_ARCH="" check

In step 4, it shows that
