[Buildroot] [PATCH] package/gauche: fix 'dlfcn.h: No such file' on autobuild

[Hiroshi Kawashima]

Ported from bdwgc package.
When build with BR2_STATIC_LIBS environment, prevent to use dlopen().

Fix:
http://autobuild.buildroot.org/results/da5/da5b9605552d4914c5e6f0d890367b92536419c1

If you do this, then add -std=gnu99 in GAUCHE_CFLAGS. Like:

GAUCHE_CFLAGS = $(TARGET_CFLAGS)

# Detection of c99 support in configure fails without WCHAR. To enable
# automatic detection of c99 support by configure, we need to enable
# WCHAR in toolchain. But actually we do not need WCHAR at gauche
# runtime. So reuesting WCHAR in toolchain just for automatic detection
# will be overkill. To solve this, explicitly -std=gnu99 is specified
# here.
GAUCHE_CFLAGS += -std=gnu99

ifeq ($(BR2_STATIC_LIBS),y)
GAUCHE_CFLAGS += -DGC_NO_DLOPEN
endif

GAUCHE_CONF_ENV = CFLAGS="$(GAUCHE_CFLAGS)"

Best regards,

Thomas
