Description A. Wilcox (awilfox) 2015-07-05 18:05:28 UTC
The attached patch adds musl support to config.site.

I enjoy playing around with porting and running Gentoo on various bits of hardware I have around the house.  Some of these machines relics (old Pentium i586), some of them are very powerful (quad-core ARM, dual PPC G4, dual-core MIPS).  I have been toying with using the musl libc on the older machines.  However, I need a separate config.site for musl as it has some pretty wild differences compared to glibc and putting them in the default 'linux' file doesn't make much sense.

As I pin down further what are red herrings and what are actually necessary, I may follow this up with another patch adding my linux-musl and i386-linux-musl files.

Reproducible: Always

Steps to Reproduce:
1. # crossdev powerpc-apple-linux-gnu 
2. # crossdev i586-pc-linux-musl
3. Try to emerge, say, sed on the musl one (or almost half of @system).  It needs ac_use_included_regex=yes in the autoconf site include.  But glibc does not need it.

Actual Results:  
Packages such as procps, sed, coreutils won't merge on musl due to needing specific definitions in the autoconf site include.

Expected Results:  
The ability to merge @system.

    site: add linux-musl
    
    Follow-up to 8b1b79e02cc36bc6f2b5583db6aeea333fb8d59b.
    
    Sets
    ```
    ac_cv_func_malloc_0_nonnull=yes
    ac_cv_func_realloc_0_nonnull=yes
    ```
    ... to sort out flex and a bunch of other packages, like procps.
    
    I was wondering why this never seemed to come up when doing cross
    for other "standard" targets which we know work and are used often;
    the answer is that we never had the -musl suffix CHOSTs covered.
    
    (e.g. linux-gnu already has this set.)
