In "perl: fuse configureFlags" [1] the effects of the preConfigure
phase were merged into configureFlags. After this change values with
spaces do not reach the configure script intact.
The only flag this affects is `ldflags` for Aarch32 and Mips, and perl
builds without it on armv7l-linux so it's probably no longer required
on any platform.
Fixes:
configuring
configure flags: -de -Dcc=cc <...> -Dldflags=\"-lm -lrt\"
./Configure: eval: line 1677: unexpected EOF while looking for matching `"'
./Configure: eval: line 1678: syntax error: unexpected end of file
Configure: unknown option -lrt"
