We've had reports of a couple of issues building against musl libc.
Issues reported:
- build procedures utilize col for Guidebook-creation, and col
is deprecated in distros that use musl libc
- some of the CRASHREPORT code is using library functions that
are not available in the musl libc environment. The reported
functions were backtrace() and backtrace_symbols(), which use
header file /usr/include/execinfo.h.
So we'll try to accommodate this. Since we don't have a means of
autodetecting the musl libc situation during the build (as of yet), the
builder will have to specify 'make musl=1' on the make command line.
Specifying 'musl=1' on the make command line will:
1. ensure that NOCRASHREPORT gets defined in the C preprocessor.
2. set COLCMD to be '../util/stripbs' instead of 'col -bx'.
