Fixed identation in subshell in build files of following packages:

base/{busybox,enchant,fftw,kmod,llvm,musl}
Replaced CFLAGS and related CFLAGS with += operator for cleanliness
Fixed mkdir commands in:
base/{exiv2,fmt,glib,json-glib}
Fixed file/recompile_magic.mgc.sh script by discarding /usr in base/file build file
Tuned build options in base/flac
Discarded unnecessary CPPFLAGS and printf command in base/flex
Replaced CFLAGS with LDFLAGS in base/gawk
Discarded /usr/bin/update-mime-database with own /etc/rc.d.rc.gtk liner in base/glib's doinst.sh file
Discarded CXXFLAGS liner in base/glib
Discarded mkdir liner in base/initfs
Cause base/llvm build file to properly cd into the smbuild directory smoothly when attempting a rebuild in future
Discarded unnecessary CFLAGS options in base/mksh
Upgraded base/zstd to 1.5.2, rewrote its build options to use cmake build system
