This option makes ld use DT_RUNPATH instead of DT_RPATH. DT_RPATH is
generally considered bad because it takes precedence over
LD_LIBRARY_PATH. For example, eog is linked with -rpath /usr/lib/eog,
and with DT_RPATH if an old eog is already installed we are basically
impossible to debug a new eog build w/o overwriting the system
installation first or explicitly using "ld.so --inhibit-rpath" to
invoke it.
This "new" actually means "new in 2000," it's 24 years ago and all other
distros has enabled it. Thus I guess some unexplainable "test suite
uses installed library instead of the just built one" issues in BLFS are
actually caused by this difference: the package author just assumes
everyone is using DT_RUNPATH thus they just set LD_LIBRARY_PATH and
consider it enough to test with the just built libraries, but DT_RPATH
breaks this expectation.
Let's eliminate the difference as it seems not doing anything good and
doing so just takes one switch.
"gcc(1)" is really not a file name.
Use <ulink> and link to the online man page on
https://man.archlinux.org/ so the user can refer to the man pages more
easily.
The change is done via a sed command and long lines are wrapped
manually.
Disable building nscd in glibc.
Update to iana-etc-20230929.
Update to vim-9.0.1968.
Update to openssl-3.1.3.
Update to meson-1.2.2.
Update to man-db-2.12.0.
Update to linux-6.5.5.
Update to kmod-31.
Update to kbd-2.6.3.
Update to gettext-0.22.2.
Update to bc-6.7.0.
I've not bothered to write an explanation for --disable-crypt because it
will likely be the default of Glibc-2.38, then we may drop it from the
command lines.
Update the rationale for min-kernel in hostreqs. Add a note in
general.ent about the EOL of current min-kernel. Realign the
backslashes in glibc instructions.
"The command below shows an example of nested command substitution
using two methods: backquotes and a $() construct. It could be
rewritten using the same method for both substitutions, but is
shown this way to demonstrate how they can be mixed. Generally
the $() method is preferred."
We need to enable decimal float here or MPFR will be built w/o decimal
float support. Then 2 of 183 tests will be skipped, and this will also
cause an ICA issue.
Q: Why we need decimal float in pass 1?
A: We need pass-1 GCC with decimal float support to build decimal float
routines in pass-2 libgcc.
We only need a one-line change in upstream fix (because we don't use
"make --shuffle"). Add it as a sed for both Chapter 5 and Chapter 8.
Note that the "minimal" sed would be '/MAEKFLAGS :=/s/r/ -r/'. I
included an additional ')' so it won't modify "-r" again to "- -r".
Tested "make" and "make check" on a x86_64 with -j8 and an arm64 with
-j24.

When I changed the sanity check to remove the "dummy.c" file, I
inadvertently used "gcc" instead of "$LFS_TGT-gcc". Which of course
finds the host gcc...
