[tex-k] speed of kpsewhich to get value of TEXMFLOCAL

[Akira Kakuto]

Dear Reinhard,

> Why are SELFAUTOLOC and TEXMFLOCAL treated differently?

SELFAUTOLOC, SELFAUTODIR, SELFAUTOPARENT, and SELFAUTOGRANDPARENT
are putenved at runtime, while it requires to read texmf.cnf's to
obtain TEXMFLOCAL.   SELFAUTOGRANDPARENT is new in TeX Live 2014.

Thanks,
Akira
