.if ${MACHINE_ARCH} != "alpha"
COMPILER = base-clang ports-gcc base-gcc
.endif

If alpha is using ports-gcc by default, then add an else to the
conditional.

Add "MODGCC4_ARCHS= ${GCC49_ARCHS:Nalpha}"

Compiling ninja on alpha

[Martijn van Duren]

Hello,

Trying to build ninja on alpha fails with the current COMPILER-line.
Apparently gcc-8 has a regression for its alpha backend resulting in a
compiler crash with the following error (transcribed):
./src/deps_log.cc:306:1: error: unrecognizable insn:
}

(insn 483 482 484 36 (set (reg:DI 262)
(plus:DI (reg/f:DI 65 virtual-stack-vars)
  (const_int -524292 [0xfff7fffc] "./src/deps_log.cc":228 -1
(nil))
during RTL pass: vregs
./src/deps_log.cc:386:1: internal compiler error: in extract_insn, at 
recog.c:2304

Is there an easy way to prioritize base-gcc over ports-gcc on alpha,
because I don't think we want to change the line to:
COMPILER =  base-clang base-gcc ports-gcc
