Modify some tests for absolute trees containing whitespace.

[Ralf Wildenhues]

I'd appreciate a review on this.  Note it includes the nontrivial bits
from the multlib.test posted a while earlier.

My question about these changes it not whether they are correct in the
sense that the test is functional afterwards, but whether the tests
still exercise what they were originally intended to do.

Thanks,
Ralf

    Modify some tests for absolute trees containing whitespace.
    
    * tests/missing.test: Use "./missing" instead of "`pwd`/missing".
    * tests/missing2.test: Likewise.
    * tests/mmodely.test: Add `pwd` to $PATH instead of absolute
    references to myyacc.sh and mylex.sh.
    * tests/multlib.test: Likewise for mycc.
    * tests/txinfo26.test: Skip if `pwd` contains whitespace, as
    an absolute --srcdir does not work there.
