* Removed sourcebuildfile function call in various functions to cause sourcing to happen only once
* Added code that invokes /etc/rc.d/rc.gtk whenever /share/applications directory is detected
to update a system's GTK cache
* Added more stuff in TODO
* Rearranged code that sources bldpkg.conf a few lines up
* Renamed function debugmode to tracemode
* Defined setbuildfile, autoextractmode, displaysummary and setcputhreads functions and added corresponding option letters to getopts
* Added explanation in the help function
* Added temporary commented code for detecting stripped binaries and libraries before they are actually stripped
* Discarded -exec rm -v since the find command already contains -delete
* Discarded --strip-unneeded option from strip command
* Miscellaneous fixes
* Added an if/else condition for adding package description correctly inside installpkg script, part of base/pkgtools
* Temporarily removed epiphany from net
* Upgraded extra/gthumb to 3.11.2
* Fixed variables in extra/{libass,rdesktop,scrcpy,sdl,sdl2}
* Fixed variables in gtk/{gnome-icon-theme,gst-plugins-*,libsigcpp,pygobject3}
* Discarded old CHKSUM512 files from gtk/pygobject3
* Added a fix to remove a gcc option that caused net/hexchat to fail
Upgraded chrony to version 4.2 and fixed its runit build script
Replaced $ARCH variable with $arch to cause gmp and db builds in base srction to build correctly
Fixed descriptions in xcb-util-image and xcb-util-wm in xorg section
Removed drm option in xorg/mesa and added llvm as a dependency
* Cause perl compile to fail prematurely if /usr/local/include directory exists. This directory
is unfortunately a preset fallback directory searched by gcc for some rust applications that
otherwise fail to compile for want of gcc toolchain-specific C++ headers that are otherwise
present in standard locations
* Fixed net/mutt homepage URL
* Fixed code that prevented writing to BUILDMONITOR.html when $showsummary was set to 0 by moving it into its own separate function
* Also moved out code for cleaning up build files into a separate function
* Made miscellaneous fixes and removed unnecessary code
* Removed redundant code that checked for usr/var directory inside the staging directory since the existence of usr is already checked in previous lines
