Faça um backup e substitua o arquivo /etc/makepkg.conf.

Ele é o arquivo responsável pelas configurações que serão utilizadas para compilações de pacotes no Arch atraves dos PKGBUILD oficiais ou do AUR, que posteriormente serão instalados através do pacman.

Nessa configuração, o compilador irá usar as flags específicas do seu processador, acelerando a compilação e tornando o binário mais rápido para seu sistema.

Nesta configuração, está desabilitada a compressão do pacote compilado (a compressão é interessante apenas se você deseja disponibilizar o pacote via rede).

As opções na parte inferior "export CC=clang" e "export CXX=clang++" podem ser habilitadas caso queira compilar utilizando o LLVM em vez do GCC.

Bom dia, li este artigo e fiquei curioso para saber mais sobre estas "FLAGS" que também são comuns no GENTOO. Na linha postada:
"#-- Make Flags: change this for DistCC/SMP systems
MAKEFLAGS="-j5"" ---> Vem a DÚVIDA: Meu notebook é um Dell iCore 3, então a sintaxe correta para o meu caso seria;

MAKEFLAGS="-j3" ???

use o numero de núcleos de seu processador + 1.

uma das maneiras de se descobrir:

grep "model name" /proc/cpuinfo | wc -l

Ok, obrigado por me responder.
Irei testar mais tarde.

Companheiro digitei o comando grep "model name" /proc/cpuinfo | wc -l ele mostra a quantidade de nucleos que o meu processador possui?

sim, pode usar também o comando nproc.
