Yann E. MORIN 72703d02b9 support/dependencies: check that PATH does not contain CWD
A person on IRC reported a build failure with the util-linux package,
looking like this:

for I in uname26 linux32 linux64        ; do \
	cd /home/aep/consulting/chargery/tracker/output/target/usr/bin && ln -sf setarch $I ; \
done
[...]
/bin/sh: line 1: ./ln: cannot execute binary file: Exec format error
/bin/sh: line 1: ./ln: cannot execute binary file: Exec format error
/bin/sh: line 1: ./ln: cannot execute binary file: Exec format error

The issue was an empty path in the PATH variable, which means "current
working directory", causing a "ln" binary built by util-linux for the
target to be used instead of the system-provided "ln".

We already check a number of things in the PATH and LD_LIBRARY_PATH
variables in support/dependencies/dependencies.sh, but we were not
checking that PATH did not contain an empty path.

This commit fixes that and takes this opportunity to simplify the test
code for PATH and LD_LIBRARY_PATH.
