--with-cpu=armv7 is not a valid configure option, since -march=armv7 means
the common subset of v7-A, v7-M and v7-R, which cannot be used to build
glibc (most .S source files expect to be built in ARM mode, not Thumb-2).
These directories are expected to be selected on the basis of
autodetection of what architecture $CC $CFLAGS $CPPFLAGS builds for, not
using --with-cpu configure options.
