Could not load ice on alpine

[waghanza]

Hi @mruz,

Following the-benchmarker/web-frameworks#3655 (comment), I added a flag on phpize for alpine (first time I do such a thing).

@see DataDog/dd-trace-php#312

This allow support for alpine since I have a debug symbol loading issue (and then extension could not be loaded).

Regards,

PS : I'm not sure why this debug symbol is required, btw

PSS : I'm not sure travis will help, if you want that ice support alpine

Thanks @waghanza, I will test it.
If it works we will need to update in zephir, as config.m4 is overridden when we regenerate the sources.

@waghanza adding lexecinfo flag works.
I will think how to add it permanently, but in meanwhile, can you try to export the flag before you install ice:

export LDFLAGS="-lexecinfo"
pecl install ice

PS. Or you can add it to the docker environment variables
