bug#48155: [dejagnu-1.6.3-rc4] make check depends on SHELL

[Kiyoshi KANAZAWA]

Hello,
Tried dejagnu-1.6.3-rc4 on Solaris x86/x64 with many SHELLs & found
make check fails with SHELL=/bin/csh,
which does not occur with dejagnu-1.6.3-rc3.
I know csh is not recommend, but still have to say something changed worse.

$ uname -a
SunOS hidden 5.11 11.3 i86pc i386 i86pc

$ gcc --version
gcc (GCC) 10.3.0

$ echo $SHELL
/bin/sh
$ ./configure CC=gcc
$ make
$ make check
  :
                === runtest Summary ===

# of expected passes            294
DejaGnu version 1.6.3-rc4
Expect version  5.45.4
Tcl version     8.6


On the other hand,
$ SHELL=/bin/csh export SHELL
$ ./configure CC=gcc
$ make
$ make check
  :
                === runtest Summary ===

# of expected passes            258
# of unexpected failures        36
DejaGnu version 1.6.3-rc4
Expect version  5.45.4
Tcl version     8.6
