Support building on systems with undefined PATH_MAX, e.g. GNU Hurd.
Simple, but not ideal solution yet - PATH_MAX is assumed to be 4096. -
Stop assuming that LDFLAGS has flags only for the linker (LD).
It used to be true long time ago, when these flags were passed
directly to ld. Nowadays (for quite many years already) it happens
differently and ld is almost never called directly during build,
because it's the compiler that is used for performing linking stage
(so called CCLD, practically almost always the same as CC).The build process was already using CCLD (defaulting to CC's value),
but was prefixing all unprefixed flags in LDFLAGS with -Wl, prefix,
making it impossible to pass non-linker flags via LDFLAGS to CCLD.
No more! Now it's assumed that LDFLAGS are meant to be passed to
the compiler, so linker flags require explicit -Wl, prefix.
