Disable GCC sanitizer runtime libraries. They are not needed for the temporary installation. In <xref linkend='ch-tools-gcc-pass1'/> it was implied by <parameter>--disable-libstdcxx</parameter>, and now we can explicitly pass it.
 
Linux From Scratch/chapter08_gcc — Chinese (Simplified Han script)
GCC may need more stack space compiling some extremely complex code patterns. As a precaution for the host distros with a tight stack limit, explicitly set the stack size hard limit to infinite. On most host distros (and the final LFS system) the hard limit is infinite by default, but there is no harm done by setting it explicitly. It's not necessary to change the stack size soft limit because GCC will automatically set it to an appropriate value, as long as the value does not exceed the hard limit:

The <phrase revision='sysv'><filename>utmp</filename>, </phrase><filename>wtmp</filename>, <filename>btmp</filename>, and <filename>lastlog</filename> files use 32-bit integers for timestamps and they'll be fundamentally broken after year 2038.

Linux From Scratch/chapter04_settingenviron — Chinese (Simplified Han script)
For many modern systems with multiple processors (or cores) the compilation time for a package can be reduced by performing a "parallel make" by telling the make program how many processors are available via a command line option or an environment variable. For instance, an Intel Core i9-13900K processor has 8 P (performance) cores and 16 E (efficiency) cores, and a P core can simultaneously run two threads so each P core are modeled as two logical cores by the Linux kernel. As the result there are 32 logical cores in total. One obvious way to use all these logical cores is allowing <command>make</command> to spawn up to 32 build jobs. This can be done by passing the <parameter>-j32</parameter> option to <command>make</command>:

By default, the linker would generate both the GNU-style hash table and the classic ELF hash table for shared libraries and dynamically linked executables. The hash tables are only intended for a dynamic linker to perform symbol lookup. On LFS the dynamic linker (provided by the Glibc package) will always use the GNU-style hash table which is faster to query. So the classic ELF hash table is completely useless. This makes the linker only generate the GNU-style hash table by default, so we can avoid wasting time to generate the classic ELF hash table when we build the packages, or wasting disk space to store it.

An astute reader may wonder why a <quote>triplet</quote> refers to a four component name. The kernel field and the os field began as a single <quote>system</quote> field. Such a three-field form is still valid today for some systems, for example, <literal>x86_64-unknown-freebsd</literal>. But two systems can share the same kernel and still be too different to use the same triplet to describe them. For example, Android running on a mobile phone is completely different from Ubuntu running on an ARM64 server, even though they are both running on the same type of CPU (ARM64) and using the same kernel (Linux).
