[kwilczynski: commit log, move .*.cmd before .*.d to

$(or ...) is available since GNU Make 3.81, and useful to shorten the
code in some places.

Covert as follows:

  $(if A,A,B)  -->  $(or A,B)

This patch also converts:

  $(if A, A, B) --> $(or A, B)

Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".

Anyway, preceding spaces are not significant in the code hunks I touched.

The values in param may be random if they are not initialized, which
may cause use_dma flag set even when "-d" option is not provided
in command line. Initializing all members to 0 to solve this.

The commit c9a707875053 ("tools pci: Do not delete pcitest.sh in 'make clean'")
fixed a `make tools clean` issue and simultaneously brought a regression
to the installation process:

  for script in .../tools/pci/pcitest.sh; do	\
	install $script .../usr/usr/bin;	\
  done
  install: cannot stat '.../tools/pci/pcitest.sh': No such file or directory

Update the install commands to fix the remaining issue.
