From 8a1ef667769653eb5b00c7d097321e58fdcf602e Mon Sep 17 00:00:00 2001 From: "Guillermo E. Martinez" Date: Mon, 13 Jun 2022 08:34:26 -0500 Subject: glibc: configure adding debug symbols in glibc build After building the cross toolchain and compile a simple C program, objdump reports debug information even though -g modifier was not used. These debug segments are in glibc library and CRT files. So a new config entry: CT_GLIBC_ENABLE_DEBUG was added to control when we want to add debug information to glibc, by default is enabled.
