Test cases:
Building firefox 48.0, gcc 6.1.0 and hello_world.c,
hello_world compiles with -fsanitize={address,memory} and without.

toolchain-23:
binutils 2.27
gcc 6.1.0
gcc-libs 6.1.0
glibc 2.23
libtool 2.4.6
linux-api-headers 4.7

Every program builds and executes without errors.

toolchain-24:
binutils 2.27
gcc 6.1.0
gcc-libs 6.1.0
- glibc 2.23
+ glibc 2.24
libtool 2.4.6
linux-api-headers 4.7

firefox 48.0 passes two build stages: build and package from clent.mk for make.
Build stage passes without errors, package stage fails.
Fails presumably due to parsing error in configuration text files, reported in
Arch  FS#50231 - [firefox] cannot compile firefox 48.0 - error in client.mk

gcc 6.1.0 fails on every ASAN test.

hello_world.c -fsanitize={address,memory} programs build against 2.23 and 2.24.
Programs fail to execute with glibc 2.24, execute with 2.24.
