perf tools: Makefile: Remove various and sundry cruft
This commit squashes several commits that remove:
unnecessary uname calls
`sh -c'
BUILT_INS and QUIET_BUILT_IN
They have no effect, and the `fixup-builtins' and `check-builtins.sh'
scripts don't even exist.
RUNTIME_PREFIX
It's currently never anything but unset, and it's apparently
only meaningful when Microsoft Windows is the operating system
(according to the source for git).
TEST_PROGRAMS
EXTRA_PROGRAMS
unused SHELL_PATH_SQ portions
unused test for V=2
useless exports
Only when `V' is undefined (that is, only when the value of `V'
is empty) is `export V' performed, which just has the effect of
placing the empty-valued variable `V' in the environment.
The only other script to make use of `V' is `Documentation/Makefile',
which only checks whether `V' is undefined (that is, whether the value
of `V' is empty); hence, the `export V' has no effect whatsoever.
Similarly, `export QUIET_GEN' is useless because it will only have
a non-empty value when `V' has an empty-value, and when `V' has
an empty-value, `QUIET_GEN' is always explicitly set in every
script in which it is used.
`DESTDIR' is only ever defined by the user via the environment
or the command line, both of which are automatically exported
to sub-make processes. Furthermore, no non-make sub-scripts
make use of `DESTDIR' as an environment variable.
No other scripts use `perfexec_instdir'.
unused QUIET_SUBDIR{0,1}
TAR and RPMBUILD
PTHREAD_LIBS
Maintainer's dist rules and commands
distclean target
Test suite coverage testing
PRINT_DIR and NO_SUBDIR
`configure' target
NO_CURL
@@PERF_VERSION@@ substitution
Without the sed command, all of the rule's commands can be reduced
to a single line that copies a file and sets the permissions properly
in the process.
`make test' echo line
template_instdir
PERF-BUILD-OPTIONS
double-colon rules
The use of double-colon rules seems misguided or vestigial git.
Essentially hard-coded $(SCRIPTS) expansion
