This would appear to be related to the ld version check for VDSO failing. awk: /home/kisskb/slave/src/scripts/ld-version.sh: line 4: regular expression compile failed (missing '(') .*) /bin/sh: 1: [: -lt: unexpected operator I.e. this line: gsub(".*)", ""); appears to be trying to turn e.g. "GNU ld (Gentoo 2.25.1 p1.1) 2.25.1" into " 2.25.1", so perhaps the bracket should be escaped. What version of awk is it using? (GNU Awk 4.0.2 works for me). Can somebody experiencing this please try: ${CROSS_COMPILE}ld --version | ./scripts/ld-version.sh with the following patch, to see if it helps.
