Subject: package/gcc: disable libsanitizer for uClibc
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=554e29e267e6b36a0fd78c82cbad2c82d939eb7f;p=buildroot.git

package/gcc: disable libsanitizer for uClibc

libsanitizer requires wordexp() support which we lack in our current
default uClibc configurations (and it's fat & big).
Hence disable it when the toolchain is uClibc-based.
It only affects gcc 4.9+ since it's default on now for supported
platforms.
