From 305ab0a748c52eeaeb01d8cff6408842d19e5cb5 Mon Sep 17 00:00:00 2001 From: Randy Dunlap rdunlap@infradead.org Date: Wed, 25 Jun 2025 00:30:54 -0700 Subject: [PATCH] parisc: Makefile: explain that 64BIT requires both 32-bit and 64-bit compilers
For building a 64-bit kernel, both 32-bit and 64-bit VDSO binaries are built, so both 32-bit and 64-bit compilers (and tools) should be in the PATH environment variable.
